If you create a text shortcut with the shortcut being a number (DOB, telephone number, staff number etc) and then you try to enter that number anywhere in iOS (web page, email or any app) it is impossible. The number you input enters incorrectly. EG: I have created a shortcut of "ss" for my staff number 17898887. However it is now impossible to enter any number beginning 1789 anywhere in iOS. As you as you type the first few numbers, the actual number you select does not display. EG enter 1789 and it will enter 178& or 1787 or 178£ and you have to constantly go back and correct it. I can reproduce the error on any iOS 7 device. It never happened before upgrading.
