Does MIDI monitor show the expected values triggering when you press? If so either messages aren’t reaching the pedal or the pedal isn’t responding as expected I would guess.
I think I know why I was having a problem. I was expecting the Engage Preset function to jump to that preset. The function does indeed engage the correct preset, but it does not jump to it on the LCD display. I guess the only function that jumps is Bank Jump. Am I correct?
