*Error* eval: undefined function -xxxxx_mosDisplay while using abConvertComponentParams.il to change device between different PDK

Dear Andrew,

I want to change umc80nm device to umc55nm device in all schematics of my Library, but get *Error* eval: undefined function -xxxxx_mosDisplay while using abConvertComponentParams.il to change device between different PDK.

I load "abConvertComponentParams.il" and "abInvokeCdfCallbacks.il" and use the following function in CIW:

abConvertComponentParamsForLib("xxxx(my Library name) "schematic" "../../conv.config")

My conv.config file(for change NMOS as example):

Although the device seems correctly changed, I can not modify any parameter in the property of instance (as the pic below, some boxes are grey) 

CIW also shown these Error:

How can I solve this problem?

Thanks
