Movie set listings

I have come accross an odd bug in the movie sets. In the movie browser if I select a movie set, then click the magnifying glass to show only movies in that set, that works fine. If I then select none and click the magnifying glass again, it shows all the movies in the list apart from those in the set I just looked at.

For me I get a different result...

After pushing the magnifying glass after selecting NONE, I get none showing, I have to reset filters to see any movies again.
