Lich calibration problem

I’ve finished building lich, upgraded firmware to v22.4.0 and encountered a problem while trying to calibrate CV input. High measured 5.03, low measured -4.98, clicked ‘Calibration’ then clicked ‘Store settings’ and moment after that my number display goes dark and buttons light up in order: left, right, left, right, left, right and then left stays on. Module is unresponsive after that unless I reset power in my rack, then it’s back on but the calibration is not preserved. Any one encountered something similar?

Yes, to calibration issues not being preserved in latest firmware. I was told to roll back to a previous firmware (think it was v22.0 but search forum to find it) till this if fixed.
