I noticed today my sons account does not show any movies from a collection unless everything in that collection meets the criteria for it to be allowed for him to watch. I use labels to keep him from watching inappropriate things just as much as narrowing his selection down. There is one collection I only want him to have a single movie from. It only shows up if you use a filter that would include it. Not in the main view.
The issue in connection with sharing labels is already known and filed as a bug.
