Season is not showing

[Hallo123]

I have a problem with a series where the seasons aren't displayed, but that only happens in my main library.

I created a test library and the seasons are displayed in it.

I have already deleted the series several times and restarted the server but the seasons are not displayed

I copied the folder from the test library to my main library but it still doesn't appear

Jellyfin v10.11.1


Please help
