Plex will not add all my new folders and shows series i long since deleted. Despite scanning library

I already have read permission enabled for it. should i change it to include write?

update: i forgot to check the subfolder. I am doing that right now, and will rescan the libraries upon its completion

further update. Still no changes after doing the plex dance again. rescanned, emptied trash, cleaned bundles, and rescanned. I still see shadows and titans in the tv shows.
