Ok, I'll follow your lead and accept there are shows in the library.

My next best guess is Item 1e here... https://forum.kodi.tv/showthread.php?tid=336969

Thanks, that looks like it might be a good lead!
There are tons of tvshow.nfo files with the wrong url in a bunch of the shows (might even be the ones giving me grief)
I tried fixing the one for Grey's anatomy and refreshed it from the webinterface - ran another scan but still the episodes on disk are not added to the library.
