Pinned support topic for metadata in Plex TV Series agent that needs fixing?

I’m a new Plex premium user and I am pretty frustrated at the state of my scanned TV Shows. Although I have perhaps 100 series, Plex displays about 8 series and dumps sometimes 100’s of random files under a show. Renaming at least some of the affected folder/files according to the guidelines and doing the Plex dance does not address the issue. It seems to ignore the file naming completely. See example screenshot of the mess that is created. I hope this is all user error and that there is an easy fix that I’m missing. Please advise.
