Hello,
in our setup we use category hierarchy for a better structure, too, most entries are not linked to a parent category, but to subcategory only. On the map’s category list we need the total count for parent categories, including subcategories. So we changed the function geodir_filter_empty_terms() in geodirectory-functions/general_functions.php lines 4786-4798. Maybe you are interested in this code, too.

Dear developers, we would be very glad if you implement this code into the next version. Otherwise could you please add a hook that we can modify it without hacking the code?

function geodir_filter_empty_terms($terms) {
    if (empty($terms)) {
        return $terms;
    }

    $return = array();
    foreach ($terms as $term) {
        if (isset($term->count) && $term->count > 0) {
            $return[] = $term;
        } 
	else if(!empty($term)) {
		$count = 0;
		$taxonomy = $term->taxonomy;
		$args = array(
			'child_of' => $term->term_id,
		);
		$tax_terms = get_terms($taxonomy,$args);
		foreach ($tax_terms as $tax_term) {
				if( $tax_term->count > 0) {
					$return[] = $term;
					break;
				}
		}

	}
    }
    return $return;
}

Suggestion for a filter hook:

...
	else if(!empty($term)) {
		$return = apply_filters( 'geodir_filter_empty_terms_filter', $term);

	}
