Custom Tag Description unable to display just below and outside of the Loop

Hello StackExchange Team! In my wordpress tags for custom post type, the code ?php echo term_description();? or outputs fine just outside and above the loop.

The problem I am having is that the same tag_description is blank when placed outside and below the loop below.

?php
                            $countries_location = '';
                            $countries_location = apply_filters('zeetume_site_location_ads', $countries_location, 'search');
                            if (get_query_var('paged')) {
                                $paged = get_query_var('paged');
                            } else if (get_query_var('page')) {
                                // This will occur if on front page. 
                                $paged = get_query_var('page');
                            } else {
                                $paged = 1;
                            }

                            ? 

Please help me out, I am confused as to what the problem is.
