Acrobat Update 11.0.15 - broke Fill and sign

Acrobat Pro XI recently updated to 11.0.15 and now forms cannot be signed, If they open in Reader DC they can be signed, and if I install a trial version of Acrobat DC it works. I have tried this on 3 different workstations. All of them worked, updated them and now none of them do. When you select add signature you can see your signature, you can drag and place it where you want to, but as soon as you left click to execute. the signature disappears. Again this does not happen in Reader DC or in Acrobat DC. Only in Acrobat XI 11.0.15
