Problem: The client is experiencing issues with setting the correct translation behavior for ACF fields in WPML. Specifically, they want to change the field settings from 'copy' to 'copy once'. Despite changing field group translation settings, the fields revert back to 'copy'. The 'column-builder' field, a critical flexible content field, and its nested fields are not maintaining the 'copy once' setting as required. Solution: We reviewed the custom fields on the specified page and found that the main field 'column-builder' does not appear directly in the list of custom fields, which is typical for flexible content fields. However, its generated subfields do appear. We compared the WPML behavior of individual elements with their ACF JSON configuration and found that the settings for fields like 'acfe_flexible_toggle', 'acfe_flexible_layout_title', 'custom-colors', and 'background__layout' are correctly aligned with their respective WPML settings as 'Translate' or 'Copy once'. If you are experiencing similar issues, we recommend checking the ACF JSON configuration for each field and ensuring it matches the desired WPML setting. If discrepancies continue, please provide specific details about which fields are not behaving as expected so we can investigate further.
