Tetrapad slight voltage offset

I have a Tetrapad hooked up to a synth voice - I notice that when the Tetrapad (in Mode 1) is plugged into the V/OCT of the OSC there is a slight voltage change. This is minor on an oscillator as it’s just a few cents but it’s more noticeable on something like the Morphagene Organize CV input where the voltage change is throwing my sample slices out.

Essentially it seems like 0V on Mode 1 isn’t 0V.

Is this my unit or a known issue which is fixable?
