Rudder DR Toggle icon

Hi, I've just bought a Devo8s and this is my 1st post here. So thanks PB, FDR and others who have worked so hard on this. The result is great.

I've had difficulty enabling the rudder DR toggle icon on the main screen. I have a mode 1 radio using v3.0.0. I attach the full ini file for my model but the problem seems to be tglico2=0,0,0. The rudder icon appears when I manually edit the file to tglico2=0,3,0. Am I doing something wrong?
Thanks, David.
