Air suspension relearn trouble

Hey guys My 2012 Jeep Grand Cherokee Overland air suspension went out. I changed out all my components, All 4 Air Struts/Bags, Compressor, Valve Block, Connectors. I’m trying to have run the relearn/refill program with Full functionality OBD2 Scanner accessing the ASCM.
My problem is it won’t complete it.

I Run the Height sensor check, it succeeds and then run the rewrite suspension values and it then tells me the sensors are not calibrated, test can’t be run.

Live data shows all 4 height sensors at -100.00mm no change or fluctuations for anything.

Can anyone help me figure out why I can’t get the ecu to read height sensors?

They were just fine before I deflated the system and repaired its components. Any help would be appreciated thank you.
