Watch Status on One show resetting for some episodes

General Discussions

I’m running into a weird issue with Plex and the watch status for one specific show.

The show is “The Rising of the Shield Hero.” There are four seasons total, and I’ve watched all of them as of October 2025. The problem is that the same episodes from seasons 1 and 2 keep losing their watched status.

I’ve tried:

• Marking the individual episodes as watched

• Marking the entire season as watched

• Marking the whole series as watched

Everything looks fine at first, but after some time those same episodes revert back to “unwatched.” It’s consistent — the same handful of episodes reset every time.

What’s strange is that every other show and movie in my library is behaving normally. This issue only affects this one series.

Has anyone seen this before or know what might cause it?

Verify the health of your plex server database: GitHub - ChuckPa/DBRepair: Database repair utility for Plex Media Server databases

Do also determine which “Episode Ordering” is in effect for this series.
(There is a library default, and also a possible override just for this series)
See if there are differences about certain episode numbers between TheTVDB.com and TheMovieDB.org

I checked this morning and the unwatched Eps have changed to;
S01: E01,03,04,07,09,10,12,13
S02: E02,05,11

This is the same on 3 different accounts with access to this Plex Server.

I used the tool and it stated that my server DB was ok.

Checking the PMS databases
Check complete. PMS main database is OK.
Check complete. PMS blobs database is OK.
