Owned Steam Games

When I first started using SteamGifts, I saw that there was an option to hide all the games I already owned, I immediately did that, because it basically halved the number of pages I had to look into. Now that I bought the Origin Bundle, and that I finally won something, I thought that those games would disappear too, but that was not the case. I tried everything, I disabled the filter and then activated it again, I tried to log out and then log in back, and when I was looking in the forums to see if there was anything on the matter, I saw the addon thread and tried to install one of those, but I still see all the pages of Crysis 2, Mirror's Edge and all those other games. Is there a way to update the list of games that I already own, or it's just a time thing, and I just need to wait for it to update automatically?
Thanks for reading this, and sorry for my grammar but English is not my native language.
