Why is User Dave listed on my login?

PVZ2 has added 2 new users to my account  - User Dave and User Dave 1. I now have 5 logins. The two I use - linuxPigPen and linuxPiglet and now "h", "User Dave" and "User Dave 1". What the heck? The game sometimes starts up choosing one of these accounts and I get the new User sign in screen with no resources and the beginner instructions. I then have to close and force stop the game. I want the User Dave accounts taken off my profile immediately.
