[Закрытые] Some Media translation not displayed

Background of the issue:
I am trying to translate media and show it on the translated page. You can see the issue on this page: скрытая ссылка under En quoi l'avion est-il source d'injustice ? and Pourquoi la compensation carbone n’est-elle pas la solution ? and many other tabs.

Symptoms:
I expected to see the media translation, but instead, I got the original image.

Questions:
Why is the media translation not displayed on the translated page?
How can I ensure the translated media appears correctly?
