I've read about this several times and it's usually recommended to sign out and sign in again to solve the issue, except it doesn't solve anything cause after a couple days some of my movies start to show up twice, AGAIN, especially older iTunes extras and the most recent purchases. That's really annoying is there a definitive fix??
Also, I'm on Sierra, but is it better in High Sierra (eventhough both iTunes are of course the same version...)?
