*Some* TV shows do not have episode names or descriptions

Do check if your files are in mp4/m4v format.
If they are, they could contain internal metadata which can potentially throw off Plex’s scanners.
To avoid troubles with embedded metadata, 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.

Or fix the embedded ‘Title’ tag in your files, so it contains sensible data.

Afterwards, ‘Refresh Metadata’ for affected shows. If that doesn’t help or the tv show is ‘matched’ wrong perform the Plex Dance with the whole show.

Thanks, but as I said I did the Plex dance. After moving “local media assets” below “The TVDB”.

I looked at a few file’s metadata. Most of them were blank. One .mkv had a garbage title.
