Coupon input not displaying on 2 different sites using membership/buddypress combo

I've got registration for membership on the following two sites and both have the following:

- Only one active payment gateway (one site using PayPal Single, one PayPal Express - not sure which is better)
- Coupon codes enabled with at least one created and active
- Running BuddyPress as well
- Utilize a "Visitor" access level
- Have active subscriptions

In both cases when you click "Sign Up" next to any of the subscriptions there is a page to complete the information associated with the new account but nowhere does it say the subscription cost or include a place to enter a coupon code.

The two registration pages are as follows:

Thanks for your help - the coupons are an important part of site functionality for us!
