TV Shows unable to acces trough main menu but through "Files"

Hi all,

since some days I’m unable to acces my TV shows from within the corresponding main menu entry.
The error ist that the file is unavailable and asking me if I want to remove the entry from the database.

Nevertheless I can access the TV show from the Video – Files menu.

Can anybody helb me to debug this? I want to access the content directly from the main menu.

Log file is here:
I tried the above: first from main menu, secondly from “files”.

Thanks, Sebastian
