TAZ Pro cannot get nozzle offset auto calibration to work

This used to work just fine and for unknown reasons it has decided to stop working correctly. Firmware is updated. When extruder one probes the calibration block it works fine. When extruder 2 probes it just mashes into it like it doesn’t sense it, and from every direction. Nozzle is clean, wiring is good. I checked that Z Probe indicator comes on when it’s touching. I’ve reset defaults, I’ve zeroed the Z offset. I’ve tried everything I can think of.
