K1C filament detected in CFS extruder please unload before factory reset

K1C Keep getting Filament detected in extruded, please unload before factory reset. I have removed and replaced with new CFS extruder, CFS buffer, CFS filament detector, and hot-end PCB. Went thru error repair videos. Checked all PFTS tubbing for filament in both the printer and CFS and cleaned the attached nozzle. Still getting the same error CFS attached or removed. What is the issue to get this problem resolved

Add info I noticed the filament CFS excluder error come only on when cutter calibration is selected.
