Foror's 36 slot bag

So I just bought the 36 slot bag off the coin store. I'm not 100% sure, but I think it might be bugged? When I choose to open my bags, one of my slots is just... missing. Nothing can go in it. Am I missing something?

Currently playing on Wrath of the Lich King, Icecrown server.

Thanks in advance for any advice.

It usually gets fixed when you relog. If that doesn't fix it, wait for server restart.

Thanks for the tip. I'll try that.

Edit: That worked, thanks a ton :D
