Sensor Classic Stuck Dimmers

Hello everyone,

I have two racks controlled by Sensor Classic SR48 CEM's. One of the CEM's has 12 dimmers that are stuck on and I have not been able to figure out why. If I swap it to the other rack, the same 12 dimmers are stuck on, but in the opposite rack. 

Does anyone have any idea what may be causing this?

I have already tried re-setting the CEM in both racks, I've tried disconnecting the DMX and re-setting, nothing I have tried has helped.

I'm getting into desperation mode as we are about to enter our busy season. Any suggestions would be greatly appreciated. Thank you!
