@ardoms,
The issue is fixed by our developers. One of the active plugins or a theme blocks the comments_open() property.
We've added the following hook code in the active theme functions.php file:
add_filter('comments_open', function ($open, $post_id) {
if (get_post_type($post_id) === 'w2dc_listing') {
$open = true;
}
return $open;
}, 99999, 2);
