Auction House not showing all Rares when that requirement is selected?

Tried searching for my own item on AH to see where it was listed, had only "Rare" "1-Hand" and "Level Reduction" selected as search criteria and couldn't find my item where it theoretically should have been listed. Unselected Rare, all other parameters remained and my item showed up, even though it is a Rare item.

What gives?
