Category Thumbnail Display - How to display ONLY the main Category

I am using the eList wordpress theme.

Now on the main page, there is a thumbnail display of all the categories listed. Now, on the theme you will see that they have no sub-categories under the categories, only listings

Now in my theme, I have sub-categories, and the theme does make provision for that. See my site here and the dropdown list next to the search bar in the header to see what I mean about the subcategories

Question:

How do I only list the MAIN categories on the home page, and NOT the sub-categories of the main categories as well?

Here is the code of the home page part that controls the thumbnails:

?php
    $elist_categories_args = array( 'hide_empty' = 0 );

    if ( 'on' == get_option('elist_listings_hide_empty') ) $elist_categories_args['hide_empty'] = 1;

    if ( is_tax() ) {
        $et_term = get_queried_object();
        $elist_categories_args['child_of'] = $et_term-term_id;
    }

    $categories = get_categories( 'taxonomy=listing-category' );

    $elist_listing_categories = get_terms( 'listing_category', apply_filters( 'listing_categories_args', $elist_categories_args ) );
    $elist_category_images = false !== get_option( 'elist_category_images' ) ? (array) get_option( 'elist_category_images' ) : array();
    $et_count = 0;

    if ( $elist_listing_categories ){ ?
        section id="listing-categories"
            div class="container clearfix"
                h1?php esc_html_e( 'Listing Categories', 'eList' ); ?/h1
                ?php foreach( $elist_listing_categories as $elist_listing_category ) { ?
                    ?php
                        $et_current_term_query = new WP_Query( 
                            array(
                                'post_status' = 'publish',
                                'tax_query' = array(
                                        array(
                                            'taxonomy' = 'listing_category',
                                            'field' = 'id',
                                            'terms' = $elist_listing_category-term_id
                                        )
                                    )
                            )
                        );
                    ?

                    ?php $et_count++; ?
                    div class="l-category?php if ( $et_count % 3 == 0 ) echo ' last'; ?"
                        ?php $et_listing_category_link = get_term_link( $elist_listing_category ); ?
                        ?php if ( isset( $elist_category_images[$elist_listing_category-term_id] )  '' != $elist_category_images[$elist_listing_category-term_id] ) { ?
                            div class="thumb"
                                a href="?php echo esc_url( $et_listing_category_link ); ?"
                                    img class="item-image" alt="?php echo esc_attr( $elist_listing_category-name ); ?" src="?php echo esc_attr( et_new_thumb_resize( et_multisite_thumbnail( $elist_category_images[$elist_listing_category-term_id] ), 70, 70, '', true ) ); ?"/
                                    span class="overlay"/span
                                /a
                            /div  !-- end .thumb --
                        ?php } ?
                        div class="description"
                            h2a href="?php echo esc_url( $et_listing_category_link ); ?"?php echo esc_html( $elist_listing_category-name ); ?/a/h2
                            p class="info"?php if ( 1 == $et_current_term_query-found_posts ) printf( __('%d Listing','eList'), $et_current_term_query-found_posts ); else printf( __('%d Listings'), $et_current_term_query-found_posts ); ?/p
                            ?php if ( '' != $elist_listing_category-description ) { ?
                                p?php echo esc_html( $elist_listing_category-description ); ?/p
                            ?php } ?
                        /div !-- end .description --    
                    /div !-- end .l-category --
                ?php } ?
            /div !-- end .container --
        /section !-- end #listing-categories --
?php } ?

To pinpoint out of the above code, here is the html part that holds the dynamically populated thumbnail:

div class="l-category?php if ( $et_count % 3 == 0 ) echo ' last'; ?"
                        ?php $et_listing_category_link = get_term_link( $elist_listing_category ); ?
                        ?php if ( isset( $elist_category_images[$elist_listing_category-term_id] )  '' != $elist_category_images[$elist_listing_category-term_id] ) { ?
                            div class="thumb"
                                a href="?php echo esc_url( $et_listing_category_link ); ?"
                                    img class="item-image" alt="?php echo esc_attr( $elist_listing_category-name ); ?" src="?php echo esc_attr( et_new_thumb_resize( et_multisite_thumbnail( $elist_category_images[$elist_listing_category-term_id] ), 70, 70, '', true ) ); ?"/
                                    span class="overlay"/span
                                /a
                            /div  !-- end .thumb --
                        ?php } ?
                        div class="description"
                            h2a href="?php echo esc_url( $et_listing_category_link ); ?"?php echo esc_html( $elist_listing_category-name ); ?/a/h2
                            p class="info"?php if ( 1 == $et_current_term_query-found_posts ) printf( __('%d Listing','eList'), $et_current_term_query-found_posts ); else printf( __('%d Listings'), $et_current_term_query-found_posts ); ?/p
                            ?php if ( '' != $elist_listing_category-description ) { ?
                                p?php echo esc_html( $elist_listing_category-description ); ?/p
                            ?php } ?
                        /div !-- end .description --    
                    /div !-- end .l-category --

Paste this at the end of your child themes functions.php file

function fb_filter_child_cats($query) {

$cat = get_term_by('name', $query->query_vars['category_name'], 'category');
$child_cats = (array) get_term_children( &$cat->term_id, 'category' );
// also possible
// $child_cats = (array) get_term_children( get_cat_id($query->query_vars['category_name']), 'category' );

if ( !$query->is_admin )
    $query->set( 'category__not_in', array_merge($child_cats) );

return $query;
}
add_filter( 'pre_get_posts', 'fb_filter_child_cats' );

Ideally, place this in a plugin (so it's not overwritten when you update the theme):

function wpse_106185_elist_categories( $args ) {
    return $args + array(
        'depth' => 1,
    );
}

add_filter( 'listing_categories_args', 'wpse_106185_elist_categories' );

Alternatively, a quick fix is to edit this line...

$elist_categories_args = array( 'hide_empty' => 0 );

To...

$elist_categories_args = array( 'hide_empty' => 0, 'depth => 1 );
