Membership: Signup buttons not showing for Non-Free levels

With buddypress and membership plugins installed.
In "Membership" I have created 2 membership levels (Free and Premium), setup and activated the "PayPal Express Gateway". When I go to the Registration page the levels are displayed under "select a subscription" but only Free subscription has a "Sign Up" button displayed. As far as I can figure, I have followed the setup instruction vidoes correctly. All Levels, Plans & Gateways have been deactivated and reactivated again (a suggestion I read in the forums) with no luck.Any suggestions?
