Hidden TV reappearing

I deleted a show I purchased in order to 'hide' it, but can see it on all my other devices. When I go into my account to see hidden purchases, I don't see it there. When I go back to my library, I see that not only has it reappeared, but a whole lot of very old purchases that were 'hidden' have also reappeared. Anyone know what's going on? I am using new devices, with everything is up to date.
