Movie missing in “watched” tab

Hello I was wondering if anyone has a similar problem, or know how the issue is caused. Basically I have watched 1055 movies but when i click on the watched tab on my profile it only shows 1049. I HAVE noticed there’s an issue with ‘Rocko’s Modern Life: Static Cling’ as it shows up on my feed but not in my watched tab, and has issues when you click on the link. Not sure what the remaining 5 films are that have error.
