Analog Rytm MK2 Metronome leak

I’ve searched the forum and Google and cannot find any matches, so apologies if this has been covered before. Rytm has OS 1.70.

I have the metronome turned all the way down and turned off but I can still clearly hear the clicking, it’s actually quite loud compared to the silence that it should be when everything is muted and guessing this will be somewhat unmistakable when heard through a club system which I am playing through in two days time. Any assistance on how to silence this would be appreciated.
