I don't have this problem on my surface, not on my pc either. Try reinstalling the people app, or relink your fb and twitter acc to ur windows acc?
Oh i already tried those (i cant even find the PEOPLE app in the store - must have missed it) but didnt work for me. so i reverted the PC back to factory settings and just used a local acct and set my hotmail accts one by one (like on xbox games, music, etc). There must be some conflicts somewhere that i dont know about...

has permanent marker ink on it too, but luckily its black so its not obvious
