It is possible for a single control to drive many things. Look at the other AUX switch settings, and you will find that it is also configured to drive other things – disable these and it should behave.

Thank you!  It works now but honestly I don’t know why.  I changed “Toggle Tuner” to Foot Switch 3 (Tip + Ring) but I have no idea what that means.  I also notice something called “Increment preset” now shows Foot Switch 3 (Tip + Ring) too.  “Decrement preset” shows Foot Switch 2 (Ring).  ???????????

Sorry I’m new to the H9 for about 5 days now and don’t quite have a handle on all of it’s workings.  Awesome pedal though!
