Kwikset 912 Z-Wave Code Issue

Hello, I have a Kwikset 912 that is giving me issues. It was working great on the ring system. Then it kind of lost its mind. So I unpaired it through the ring app. But, once I paired it again I can lock and unlock it from the app. But, it will now not allow me to add our codes onto the lock. I can manually add them at the lock. But, then it will not turn the alarm system on and off. Any thoughts as too why it will not allow me to add the ring codes to the lock? I have replaced the batteries, done a factory reset on the lock, and reset the ring basestation. Thanks in advance for any advice.
