[Membership 2 Pro] Membership Pro2 Plugin update issue

I have around 15000 members on the site and close to 950 are Monthly members $5/each.

I have 1.1.1 version of the plugin installed and today when I tried to update it to latest version using your HUB / Dashboard, it updated the plugin but all 15000 users including 10 thousand FREE users started showing MONTHLY membership and it gave them access to premium content.

I had to remove the plugin from plugin directory and uploaded old Plugin version manually and activated, Thank GOD I got this issue fixed but now how the heck do I update plugin?
