just got a second hand Moog Little Phatty Stage 2, the one with the USB port.
I noticed this strange behaviour with the knobs. I attached a video, because an image speaks a thousand words. In short, the LED don't follow the knobs, it's like they are mismatched, out of phase.

I have this issue with all the 4 pots. If I close them at zero, the LEDs are stuck at about 10 o'clock (see images below)
