shortcode order for event custom post type

ok im working on a website using post type event with post_meta event_start_date, i created a shortcode and everything is displaying fine except for it displaying in order, it seems as its not displaying by using meta_key nor meta_value. this the page http://mixedbagnext.com/wordpress/events/ you'll notice the date order is wrong, i want it to display the most recent date first then the other dates following. side note im using more fields plugin to create post_meta and is set to date entered 2015-01-01. here is my code

    // SHORTCODE event
function event_shortcode( $atts ) {
extract( shortcode_atts( array( 'limit' = -1, 'type' = 'event'), $atts ) );   

$eventlist = '';

$paged = get_query_var('paged') ? get_query_var('paged') : 1;  

$carousel_query = new WP_Query(array ( 
    'posts_per_page' = $limit, 
    'post_type' = $type, 
    'post_status'  =  'publish',
    'order' = 'DESC',
    'orderby' = 'meta_value_num',
    'meta_key' = 'event_start_date',
    'meta_query' = array(
   // 'relation'  =   'AND',
    array(
            'key' = 'event_start_date',
         'value' = date('Y-m-d', strtotime('-6 hours')), //value of "order-date"
         'compare' = '=', //show events greater than or equal to today
         'type' = 'CHAR'
        )
    ),
    'paged' = $paged ));
