I am getting two issues with membership 2:
1) it's missing the username in the string "You are logged in as ". This happens in the Account page and also on the Membership 2 Login widget.
2) We had already all the admin-users, then I made the first test to register for a membership and the plugin changed by all users to one membership, instead of the "none". only the actual logged admin user was not affected, and still says "none",
