Digitone channel bleed even on hard panning

Hi!

I´m trying to sync the Digitone with Pocket Operators - T3 with a kick pulse to sync the PO´s, hard panned to the left - however I´m facing a weird bleed on the right output.

Even taking off the left output, I still can hear a faint but annoying kick pulse in the right output.

All the effects (including overdrive) are off.

Any ideas or it´s a bug? Thanks!

Metronome?
