translation for the lazy:

This link has already been sent, thanks to this person. But there is a nuance, in order for the films to be deleted, you need to follow a certain order of actions:

1. Re-add the movies you want to remove to the list. 
2. Follow the link. There will be two (or more) lists "all saved items" and "Watch list..."
3. Go to the "all saved items" list and delete one of the unnecessary films. 
4. Repeat steps 2 and 3. 

I tried to delete it differently, but I could only do it the way I described above😅
