On one of the dimmers change parameter 12 to 11. If you are using SmartThings or Hubitat you will need to edit the device code. Change this:
def getParameterNumbers(){
return [1,2,3,4,5,6,7,8,9,10,11,13,14,15,17,18,19,20,21,22,51,52]
}
to this:
def getParameterNumbers(){
return [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,17,18,19,20,21,22,51,52]
}
Then go into the device preferences and change it to 11 which will stop the loop from occurring.
