Checkout problems

It appears I have everything setup using VirtueMart and K2Mart within the Black & White theme, but I'm getting some strange behavior when trying to checkout. I'm logged in with a few items in my cart, and when I proceed to checkout, I would think it would take me to the next step, instead, it brings me to a page that has me fill in my profile information. Am I doing something wrong?

I don't want to use the VirtueMart cart if I don't have too.

Anybody have any insight on this?

Thanks.
