[مغلق] ACFML - Problems with relationship fields on secondary language

Background of the issue:
I am trying to pick and save relationship posts on a secondary language using ACFML.

Symptoms:
With ACFML active:
- The search bar does not work
- The related posts are not saved correctly and some are missing.
With ACFML deactivated:
- All works just fine.

Questions:
Why does the search bar not work with ACFML active?
Why are the related posts not saved correctly and some are missing with ACFML active?
What changes when ACFML is deactivated that makes everything work fine?
