I got the solution by applying this https://www.dfactory.eu/get_terms-post-type/ with some modifications.

Would still be nice if hide empty checks on current post type and on filters already active (but understand this no small fix).

if ( ! is_admin() ) {

  function df_terms_clauses($clauses, $taxonomy, $args) {

      if(!($args['hide_empty'] && (empty($args['class']) || $args['class'] == "beautiful-taxonomy-filters-select"))) return $clauses;

      $query_post_type = get_query_var('post_type');
      $args['post_type'] = is_array($query_post_type) ? $query_post_type : array($query_post_type);

      if (!empty($args['post_type'])) {
        global $wpdb;

        $post_types = array();

        foreach ($args['post_type'] as $cpt) {
          $post_types[] = "'" . $cpt . "'";
        }

        if (!empty($post_types)) {
          $clauses['fields'] = 'DISTINCT ' . str_replace('tt.*', 'tt.term_taxonomy_id, tt.term_id, tt.taxonomy, tt.description, tt.parent', $clauses['fields']) . ', COUNT(t.term_id) AS count';
          $clauses['join'] .= ' INNER JOIN ' . $wpdb->term_relationships . ' AS r ON r.term_taxonomy_id = tt.term_taxonomy_id INNER JOIN ' . $wpdb->posts . ' AS p ON p.ID = r.object_id';
          $clauses['where'] .= ' AND p.post_type IN (' . implode(',', $post_types) . ')';
          $clauses['orderby'] = 'GROUP BY t.term_id ' . $clauses['orderby'];
        }
      }
      return $clauses;

  }
  add_filter('terms_clauses', 'df_terms_clauses', 10, 3);

}

The code works for me, with and without Select2, BTF 1.2.9 and WordPress 4.4.2.

Perhaps it is:
– Browser specific, my test was in Chrome.
– Some other script is blocking this script.
– Jquery is not available

$('.beautiful-taxonomy-filters-select').on('change', function(){
    $('#beautiful-taxonomy-filters-form').submit();
});

My apologies, problem is solved. ‘Link this post to its children’ needs to be checked to save the connection.
