Hi Michael,
I just tried to replicate this issue but I haven't been able to replicate the behavior you reported. I would like to have you login to one of our public test portals and configure the cart the way you have your's configured and try to replicate the issue. This will determine if the issue you are reporting is with the latest version of the cart or an issue with your specific DNN portal/cart install.
Please submit a Help Desk ticket with a link to this post at the following link and I will provide you with credentials to login:
