Wah issue fix

Anyone else have an issue with their wah not working? I have my Mission expression pedal set to wah pedal>vol. Never had any issues with it working before. Now when I turn the wah on it only stays on when the expression pedal switch is engaged. I had to go into settings on my kemper stage and go to pedal settings, pedal 1, mode and change it from mono switch to another setting and switch it back to mono switch. Now it works. It turns on now and stays on till I engage the switch again. Seems like a software glitch from an update perhaps. Just wanted to put this out there incase someone else has an issue. This worked for me.
