There are certain cases on certain panes where one button seems to be an
indicator and the other functional. The AD4 general pane works this way on
one of the numbers. I have not tested the one you are talking about.
Try this test. Program using the motor tab for those items. Then close
DecoderPro and open it back up again. Then use the CV tab and see what
happens. If it stay the same as you have previously noted then we may have
a bug.
