Rule #1: don’t download or rip directly into folders which are being watched by Plex.
Always download first into a temporary folder.
Then unzip and rename the file.
Only after that move it into the Plex library.
You are using mp4 files. Those often have SPAM in them, which then leads to Plex mismatching the files.
Preparation:
Go to Settings - Server - Agents - Shows - TheTVDB
In there, grab the line ‘Local Media Assets’ with your mouse and drag it downwards, so it ends up being at the bottom of the stack of active agents.
Repeat the same under
Settings - Server - Agents - Shows - TheMovieDatabase
+
Settings - Server - Agents - Movies - Plex Movie
+
Settings - Server - Agents - Movies - TheMovieDatabase
Then revise your preparation scripts to always write a 2-digit season number in the folder names (except when the season number is 4-digit, ofc).
Nowadays it is also better to always include the year of the first broadcast of S01E01 into the folder names.
e.g. (don’t forget the ‘season’ folder)
TV\Have I Got News For You (1990)\Season 53\Have I Got News For You - S53E02 - Kirsty Young.mp4
After doing the above, perform the Plex Dance and add back each series separately.
