Description of the bug

Enabling the "Group films into collections" option causes the main library view to not update the watched/unplayed checkmark correctly, whether it is set manually or by watching an entry past the default 90% threshold.
The status is recorded correctly when opening the entry explicitly.
Restarting the jellyfin instance option causes the watched status to reflect the actual status correctly, but still prevents it from updating properly.
Disabling the "Group films into collections" option resolves the issue.

Reproduction steps

1. Dashboard->Display->Enable "Group films into collections" and save
2. Navigate to a library containing movie entries
3. Set/unset the watched status either manually or by watching the entry

What is the current bug behavior?

The watched status in the main library view does not update correctly

What is the expected correct behavior?

The watched status in the main library view must update and reflect the actual state
