Membership Plugin: Upgrade button missing or Button says No Upgrade Available on subscriptions page

I have two issues here.

Issue #1 – When someone signs up for free membership via the registration form and then they goto their subscriptions page to upgrade to a paid membership I see the area to upgrade but the button says No Upgrade Available.

Issue #2 – When I manually assigned a free membership to a user from the admin, and I goto the subscriptions page, I again see the paid membership upgrade option, but this time there is NO button at all.

I am attaching screen shots of each subscriptions page along with screenshots of the membership plans/settings.

I thought I was experiencing the same issue as the thread mentioned here

but I guess it is a different issue? Any help is much appreciated and would be more than willing to pay for premium support.
