[Membership 2 Pro] Basic profile details not updating

I'm having an issue with the Basic profile details. When I go into the member area and hit "Subscription Details" of a user and on the left hand side I want to update the basic profile details. I change the values (first name, last name, etc) and then hit save but it doesn't save. I then went to "Users" and checked that specific user and it actually did get updated in the User profile but for some reason the subscription details won't display the new values and keeps displaying the old values.

Thanks for your help! =)
