I think it is activated. You seem to have also some software active to synchronize folders. And it’s putting some status file of itself into each of your media folders.
And this change in the file system is triggering an automatic library scan

You want to avoid too frequent (and useless) library scans.
Particularly while a media file copy is in progress. Because otherwise Plex may scan incompletely copied files and generate a “signature” of them. However, the beginning of video files is very similar, because they all use the same container format. So Plex might mistake videos from different series to belonging into the wrong series.
All because it is scanning the library during file copies all the time.
So, disable FreeFileSync,
Disable the automatic library scans
Remove all the shows which intermingled
repeat the Plex dance and add shows one by one
I couldn’t find any signs of DB damage.
