Ditto Looper Volume Boost

Ditto Looper Volume Boost

Been using my ditto for a year, like it.  I played Wednesday night it was fine.  Same gear 3 nites later after a flight to next shows and the pedal is boosting gain when I click on the pedal to start or use the looper.  I’ve read a few posts on this forum but have only seen a firmware update for Ditto 2 or other products. 
Please help …
How do you reset the pedal?  is there a firmware update?  Am I going to have to replace this pedal? 

Thanks
