This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing two issues with the localization of custom fields using WPML and ACF (Advanced Custom Fields):
1. A custom field is displayed with a lock icon and is set to translate, but it does not appear in the Advanced Translation Editor.
2. An ACF field that includes a document from the media library is not visible in the list.

Solution:
We first clarified whether the ACF plugin was installed since only the Advanced Custom Fields Multilingual bridge plugin was visible. It's essential to have both the ACF plugin and the bridge plugin installed for proper functionality. We recommended checking the installation of the ACF plugin at https://www.advancedcustomfields.com/ and also suggested reading our guide on translating sites built with ACF at https://wpml.org/documentation/related-projects/translate-sites-built-with-acf/.

If this solution does not resolve your issue or seems irrelevant due to updates or differences in 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. If further assistance is needed, please open a new support ticket at WPML support forum.

Hello,
I have two problems with the localisation of custom fields:
1. there is a field that is shown with a lock (not sure why there is a lock), and set as translate, but it does not appear in the Advanced Translation Editor
2. I have an ACF field that is a document (from the media library), but I do not see this in the list.
