[Closed] custom ACF post type doesn't appear in English backend

Background of the issue:
I am trying to make our custom post types 'Reviews' and 'Landing pages' appear in the WordPress backend side menu in the English backend. When I check ACF -> post types, it says they're both a draft (CONCEPT in dutch see screenshot), while on the Dutch version they're both live. The other two custom post types (Services and Portfolio items) are live in both languages. Link to a page where the issue can be seen: hidden link

Symptoms:
I can't see the 'Reviews' and 'Landing pages' post types in the English backend. In the frontend, my reviews grid shows English and Dutch reviews mixed and double reviews.

Questions:
Why don't the 'Reviews' and 'Landing pages' post types appear in the English backend?
How can I fix the issue of mixed and double reviews in the frontend?
