Search by banned films show no results.

I noticed that if you search banned films in a determined country, it doesn't returns any result. Just go to the Parent's Guide and look for a film that has been banned in any country: UK, Ukraine, New Zealand, Singapore... None of them show the results anymore. I don't know for how much time I am having this problem but I remember that it worked fine some time ago. Now, is this happening just with me? Or it is a problem with the site?
