Missing Stacks on Dark Seal? (Possibly a Bug?)

I know this isn't game breaking or anything, but it irked me for the whole game, leaving me to wonder where the heck my 2 stacks went. I was talking to some friends and they suggested that I bought it late, but as you can see in the first image below, I bought it at the very beginning of the game.
