[Fechado] Media file issue

We have one question regarding our client (obcina-ankaran.si). They are experiencing an issue where not all media files are visible in the translated language (Italian). Some media items appear in both languages, while others are missing and must be uploaded again in the translated language. Could you please advise where this behavior is configured or controlled? We would like to ensure that all media files are properly available across the translated versions of the site.
