PO-32 dropping out of sync (SY-4)

My PO-32 is a sod to get into SY-4 and often drops out into SY-0 even though there’s a clock signal being sent in.

I used different sources - Maths, Pamela’s and LFO square wave - with the same issue.

Is this just me?

I have it in the Eurorack kit, maybe that’s to blame…?

not sure if this is it but i know when it senses that a cable has been removed
the sync setting will revert back to SY-0
