Blank cards in Munchkin 2 - Unnatural Axe?

[grv]

Hi all,

We just got a couple expansions for Munchkin, and I notice there are a few blank cards in Unnatural Axe. They are not mentioned as being in this pack on the product page, from what I can tell. Are they supposed to be?

I understand that we can make our own cards with these, which is cool, but I just wanted to make sure we were not missing any cards that should have been included in their place.

Thanks!

Steve
