Subscription Buttons Not Showing for non-Admin Users

Hi guys,

I've got Membership enabled on one of my sites and for some reason, the subscription buttons are showing up for admin-level users, but not standard users.

I have PayPal Express and Single Payments both set up and I know it's working somewhere, because when I am logged in as admin, I see this:

I have 3 subscriptions and 2 levels active so I'm not sure what's going on at this point. Let me know if you need more info.
