Showing only PAL versions of games

I'm not sure why, but when I click on the Vault, choose a console (PS3 for example) and look through the list of games from A-Z, it's showing only PAL versions. Yet when I click on the search bar at the top of the page and write in a game title, it will show all the regions of the game in the list.

I was worried that the NTSC versions had been removed, but I'm relieved it isn't the case. I'm not sure what's causing the site to do this though. Whatever the case, I thought I'd mention it so other people are aware and see if anyone else is getting one region when they look through games as well.
