List of translated texts is not displayed on the admin site.

[sinjorjob]

When I access the admin site after making various settings according to the home page (https://www.coex.cz/blog/translation-manager), the screen displaying the string data to be translated does not appear as shown below.

My screen looks like the following, with no data to be translated.
The django.po file has been generated.

Also, when I try to add translation data, the following screen appears, and I can only enter the "Admin-translation_entry-original-label:" part.

Do you know the solution to this problem?

My environment is as follows.
django:ver3.2.3
db:sqlitedb
os:windows10
