Doesn't delete paragraphs items

Hello, reviewing the database I found that the paragraphs items are not deleted (I think this happen after some update). Maybe the problem is here

$entity->getOriginalId()

As you can see here

https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Entity%21...

This method always return null and for this reason the paragraphs clean module skip the process here

if (empty($original_ids)) {
continue;
}
