GE Switches getting corrupted? Vera 3

I have via the device options tab added some change to the configuration settings. modified paramaters to make this a non dimmer by updating 7,8,9,10 to 99,1,99,1. Worked fine. Decided to revert back to normal dimming and deleted the configuration modifications. I now cannot seem to communicate to the switch. “unable to get information from node”. I have tried forcing manual updating neighbors and then configuration and no go… Was working great until I did this. This now is the 6th GE switch that just quit working on the zwave network (they work fine locally). Never had this issue on Vera 2 (coincidence?)
