[Risolto] Wrong slug for translated post

Hi, I have a custom post type (people) and I am using WPML and Yoast Duplicate Post, which should be fully compatible. But when I clone a post, let's say „John Doe“, give that post a new title „Mary Stone“, publish that post and update the translation, the slug of the translated post shows „copy-of-john-doe“, while the new post in the original language shows „mary-stone“.
