Two separate users of me

I have two different users created in Streetquest:

1st one by login through @gmail that was later connected with FB account in "Settings" of SQ

then later logout from SQ app and login in angain as 

2nd another user by FB.

These two users have currently different point numbers and they are Friends! :)

ps. initially the 1st logged user had no photo from FB. Later two of them have the same photo from the same FB Profile.
