[Résolu] Custom Post type redirects to wrong translated posts

We have a problem with the menu but also with translated items of a post type. I think something went wrong with translating. It's about the post-type Markets.

Regarding the menu: the Dutch menu (translation of the English menu) shows the wrong items.

Regarding the Markets post type: one of the original Market pages is lien caché. When I want to switch to Dutch on that page, it sends me to a blog rather than the translation of that market.
