[Решено] Media Translation not working

Background of the issue:
I have installed the media translation module and activated it. Then I uploaded translated versions of PDF files using that tool. The issue can be seen on this page: скрытая ссылка

Symptoms:
When browsing the translated content, it still shows the original PDF content instead of the Turkish version. I expected to see the Turkish version of PDFs but got the English/original versions instead.

Questions:
Why is the media translation not displaying the translated PDF files?
How can I ensure that the Turkish version of the PDFs is shown instead of the original English versions?
