keyboard short cut not working in iOS 6 on iPhone

I just tried adding a new keyboard short cut on my iPhone 4S with iOS 6 and the short cut will not stay on the phone.  I can enter it and it is added to the list of short cuts until I go back one screen, then the shor cut disappears.  This worked fine under iOS 5 and still works fine on my iOS5 iPod Touch.  Any ideas how to fix this?

Thanks

Fred
