[تم الحل] Translated page not showing all the media

Background of the issue:
We are using the theme WPRentals for our website الرابط المخفي. We have properties in English and we have created all of the Portuguese versions.

Symptoms:
The images are not showing on the translated pages. Some listings show all the images, but others are only showing 1 photo, which is the featured image. We have to add the images manually again for both versions and change the featured image for the translated listing.

Questions:
Are you aware of a similar issue?
Do you know of a solution?
