When creating and printing custom calibration sets to our KM-C6501, CWS asks for a stock that is different to the one in the calibration setup.

I create a calibration set for 170gm Coated stock that matches the setting on the printer, but when I print the calibration sheet CWS is asking for 81-105gm or sometimes even a different stock altogether.

I have tried using the factory set Coated, but this asks for Color Specific stock instead of the Coated-ML that is in the printer and has been selected.

Any thoughts anyone?
