GD is unfortunately full of sloppy bugs

look!!!:
there is in data.php:

function wp_gdsr_rating_multi($multi_set_id = 0, $post_id = 0) {
    if ($post_id == 0) {
        global $post;
        $post_id = $post->ID;
    }

    $multi_set_id = $multi_set_id == 0 ? gdsr_get_multi_set($post_id) : $multi_set_id;
    $multis_data = GDSRDBMulti::get_multi_rating_data($set_id, $post_id);
    if (count($multis_data) == 0) return null;
    return new GDSRArticleMultiRating($multis_data, $set_id);
}

do u see it ?
wrong var name $set_id and should be $multi_set_id !!!!!!
