When I try to edit ANY of my contacts (using the little pencil on the top right) it always forces me to enter a new contact. That's the only screen that comes up. I've tried lots of things, to no avail. Any clues? I can, for example, create a new contact, then immediately try to edit it, and NO, I get the "Create a new contact" screen. It must be something simple that I am overlooking.

So weird issue! 
Would you like to post a screenshot about your steps of editing a contact?
