I have episodes of the show Frasier that was produced in the 90s, as well as episodes of the new reboot of 2023. However, the server is not distinguishing between the two. It is lumping them all into the same show.
Maybe try putting the show premiere year in parentheses
Eg. Video/Frazier (2023)/Frazier (2023) S01E01.mkv
Agreed. That's what I would try too because this is how you can find them on Frasier (2023) - TheTVDB.com
Sounds like a bug. Time to report to developers
