Filter "unplayed" in collections doesn't work

[cswrd]

This issue respects the following points:

• This issue is not already reported on GitHub (I've searched it).
• I agree to follow Jellyfin's Code of Conduct.
• This report addresses only a single issue; If you encounter multiple issues, kindly create separate reports for each one.

Describe the bug

1. Go to the media library "collections"
2. Enable the filter with the tick mark to show only (partially) unplayed collections
3. Bug: still all elements are shown. Even those with a tick mark
4. FYI: this happens since I use the app. Works well in the web app. Filtering in the libraries like movies and tv series works, though.
