Problem:
The client is using ACF with WPML and has set the Multilingual Setup to 'Expert' and the Translation preferences to 'Don't translate' or 'Copy'. Despite these settings, WPML still requires the translation of all ACF field choices.
Solution:
1) Add the following code to your wp-config file:

define( 'ACFML_EXCLUDE_FIELD_GROUP_STRINGS_IN_POST_JOBS', false );

This code aims to remove the ACF label strings from the translation editor, although you can still translate them via WPML-> String Translation if needed. For more details, check the guide on AFCML core reference.
2) After adding the code, make a minor edit to the page/post in the default language and send it to translation.
3) If the issue persists, it may be necessary to recreate the page containing the ACFs and translate it again to ensure the changes take effect.
