Movies from collection getting out of the collection

[Saltyman]

Hello everyone,

I don't know if there's a fix for that but whenever I want to see the unwatched movies from library, all the movies from a collection are shown out of the collection.

So for example, I've got a list of 150 movies but when I'm filtering to "non watched", my list is growing to 400 movies. 

Is there a way to avoid that ? Thanks a lot
