So I recently opened one of my GOGmixes

http://www.gog.com/en/mix/the_best_gog_can_offer_5_star_rated_games_only

It's a mix that has 5 Star rated games only, so it's always changing - Games are added and removed, so I update it constantly

After updating it today and waiting a couple of hours...I noticed that it's not displaying at all on certain gamepages

For example: It's displaying fine on Fallout and Baldur's Gate 2 but not displaying on Wing Commander IV and The Witcher 2

Any ideas what might be causing this and how to resolve this?

Thanks!
