Advanced Custom Fields - [Local Fields] Translation Preference Issue for PHP-Registered System Fields

Overview of the issue

When registering Advanced Custom Fields (ACF) via the acf_add_local_field_group() function in PHP, the system fields within ACF, including repeater fields, are automatically set to Don’t translate. This setting disrupts the expected display of repeater fields on the front-end in translated content.

Workaround

Instead of registering fields directly in PHP, you can utilize ACF’s ability to save field group configurations as JSON files.
