Extra non-functioning radio button for variable product

Hello.

I’ve created an attribute for “Media”. In the “Configure terms” I’ve add Print and Original. I then add a price for each of these two types. When the product page renders, I have three radio buttons: a non-functioning button that appears to be the default, a Print radio button and an Original radio button. If I click either the Print or Original radio buttons, the add to cart button is enabled. However when the page first renders (the non-functioning radio button enabled) the add to cart button is not enabled. The non-functioning button is labeled print. How do get rid of this button? I have tried creating the attribute at the product level, deleted it and created the attribute for a single product and each time the non-functioning radio button is always there and always labeled print. Any ideas on how to get only Print and Original buttons to display?

Thanks.

David
