[Risolto] Copy images from gallery field (ACF)

Background of the issue:
I am trying to copy images from a gallery field in ACF so that they appear in all languages. I changed the setting to copy, and while the images show correctly in the admin panel, they do not appear on the site. I tried deleting and re-uploading the images in the source language, but it still doesn't work. The issue can be seen on this page: link nascosto.

Symptoms:
The images show correctly in the admin panel but not on the site.

Questions:
Why are the images not appearing on the site despite showing correctly in the admin panel?
How can I ensure that images from the gallery field appear in all languages on the site?
