Update W/L number in instance property, but resistor "r "value isn't change accordingly

Hi everyone

I am just using the PDK from the foundry.  I just followed its cdslib userguide. when I launch the virtuoso IC618 and create schematic. I add one instance of resistor using "add instance". in the "add instance" interface, I can adjust "W","L" value and the "Resistance" parameter (in gray) changed accordingly. 

But after I finished the placement of this resistor instance on the schematic, I clicked on its symbol and  pressed "Q". "Instance Property Editor" pop-up. It showed quite native interface: every parameter can be change (no gray area and "W" "L" shows in different places ).it was different from that of "add instance".  I changed "W" "L" and click "apply", the “W” “L” value changed displayed by symbol but the resistance value was the seem value. But CIW window give a warning "*WARNING* CDF parameter "r" reset to "6.0969K""

What I want is the resistance value display by the symbol also change after I modified "W" "L", and the "Instance Property Editor"  interface is in consistent with that of "add instance"
