Bugs with the game search on the giveaways?

So searching for Garry's Mod seems to be impossible on the site(At least for the open giveaways, changing to new does find everything).

Exists and open

Poof, gone

Edit: Same applies for Fear.

Edit 2: The search I am talking about is the built-in search after you click on the picture(in the first link) and then on the "X open giveaways were found. Click here to search." not the manual one.
