Device & User Mode after update

Version 13.0.9
PBX Firmware 6.12.65-31
Cannot add user in Device and User Mode.
No option or menu to right to add user. Replicated this on two PBXs happened immediately after update.
I am missing something, can I add a user from the User Management Module?
Under module admin what would be the module that would handle the User link under applications, Core? I assume that I could downgrade the correct module to repair?
Any Help is greatly appreciated
