[Решено] ACF Options Page (Global)

Background of the issue:
I am trying to manage fields on the ACF Options Page (Global) in WPML. Some fields are locked, meaning they are set to be copied or synchronized across languages. I am unable to unlock or change them to 'once'. Previously, there was an option with each field to choose this setting. The issue can be seen at: скрытая ссылка

Symptoms:
Fields are locked and cannot be changed from being copied or synchronized across languages. No option is available to unlock or change the setting.

Questions:
Why are some fields locked and set to be copied or synchronized across languages?
How can I unlock or change the field settings to 'once'?
