CT101 Thermostat unable to increase temp remotely

I had installed a CT101 Thermostat, I believe it may be the Iris model. When first installed I was able to set temps and adjust without problems. I set the V2 Smartthings hub to auto update device controller.

Smart things registers my CT101 as a CT100 and I recently can no longer set a temp remotely. I can often lower the temp remotely, but cannot increase the temp with either the plus sign or by setting a number.

What is likely the issue? Was the wrong update pushed to the thermostat? Is this an integration problem with the latest update on the smartthings hub?
