Hello,

I have a problem with an ACF Pro file.
The changes are available, but the JSON is not saved (see screenshot).
I am now looking for the error, but have not found the right answer on Google.
Therefore my general questions first:
1. does the name have to be unique in the entire field group? There are definitely duplicate names. Could this be a possible cause?
Write permissions are available in the folder on the server.
WP: Current version: 6.6.2
PHP: 8.1.7
ACF Pro: 5.9.0
