If there is only 1 payment method available and if you enable the "Select Automatic Payment" option through VM Configuration > Checkout,
Then there shouldn't be any payment selection, it will be automatically selected.
As i am seeing in your website. Once you get to shopping cart, it automatically selects the payment method (The name of the payment selected is: We Accept All Major Credit Cards )
I don't see any problem. Or maybe i misunderstood you. How did you get to "select payment" page, while it has been already selected?
