TheTVDB scraper combines TV Shows (corrupted?)

Having a problem over a few installations of Kodi 17.1.

Either scraping new TV Show content or fully refreshing a TV Show due to making changes suddenly Kodi is combining TV Shows together as if they were in the same folder. For example, I refreshed Black Sails and suddenly it was combined with The Simpsons. In the alphabetical listing of TV Shows, under B-L-A-C-K it read The Simpsons. Open the TV Show and all artwork if for 28 season of the Simpsons. Enter Season 1 and there’s listings for 2 episode 1’s, one for The Simpsons episode 1 and 1 for Black Sails episode 1.

I try to re-refresh Black Sails and now a third TV show has combined in.

Then adding new episodes to other TV shows suddenly combines that series with something else.

All TV Shows are in separate folders identified by proper name. There is no mixed-up overlap in the file system.

Does anyone know what is going on with Kodi and how to stop it? The only working solution I have is ti remove and then re-add all TV Show sources with several library clean-ups.

Thanks.
