Problems after upgrade to ios6

I love this app, its so easy to use, graphically beautiful, well set up. However, since I upgraded the date goes to Dec 1999, no matter what I do. And some text in the date heading overlaps. I have been unable to contact support for this. It would be very much appreciated if the creators could fix these issues.
