Problem: You are using WPML to automatically translate custom fields created by ACF for taxonomies, but WPML is not translating or copying the content of these fields. Solution: We recommend you navigate to WordPress Dashboard > WPML > Settings > Taxonomy visibility in the translation editor. Here, uncheck the "Only show taxonomy terms that haven't been translated yet" option and click the "Save" button. After saving, make a small change to the post and check the Advanced translation editor; you should now see all the fields.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please open a new support ticket at WPML support forum.
