Friends:The Maestro RRD-6ND-MS dimmer is in a triple box with two other identical dimmers. This dimmer has always worked properly for 5 years. But, when doing the Transfer of the new programming, I had a problem and deleted this dimmer under the Design tab. I then tried to add it back into the system and keep getting this error message (Incorrect device type was heard! ).The other two dimmers in the same box are listed identically to the problem one (RRD-6ND-MS). I would add a screen shot of the error, but do not see an option here to do so.Sure could use some help.Thank you, Richard
