This sounds like it may be a firmware issue. Try this:
1-Connect to a computer via USB and open up H9 Control. Backup all the presets on the pedal to a list in H9 Control.
2-Go to the Pedal tab on the app and click on Stompbox software. Reinstall the latest firmware.
3-Lastly, conduct a factory reset by turning the pedal on while holding the right footswitch & the hotknob BUTTON down. It’ll take a few seconds to reset.
That should take care of the issue, in most cases. At this point, you may download your backup preset list back to your pedal.
