Adding Pref and Qref for DERA1 model in CMLDBLDGU2

I am working on simulating a test system with CMLDBLDGU2. I realized that the DER model in CMLDBLDGU2 is the same as the DERA1 model and that needs Pref and Qref values to generate the real and reactive power as per the reference. But, these reference values are not given in the CONs of the CMLDBLDGU2. I tried measuring the real and reactive power of DER by porting them to channels from the variables list, and I observed that the values of real and reactive power from DER are zero in the simulation. I used the simulation files provided by JConto's google drive @CMLDxxU2jconto_DF20210923 folder and cmldg.py file. Clarification of this problem will be really helpful for my work.

Before the dynamic run is executed, for all loads with CMLDBLDGU2 model in the dyr file (v.34 or v.35), confirm that in the case, load table, the columns "Distributed Gen (MW)", "Distributed Gen (MVAR)" have values and "Distributed Gen Mode" is set to 'On'.
Also after the run, check the log file for error messages saying that model CMLDBLDGU2 was not assigned/ignored.

Thank you for your response. I added the real power (MW) and reactive power (MVAR) in "Distributed Gen" values, and the respective mode is set to "ON". Log file doesn't have any errors. I tried to capture the MW and MVAR from DER using the 'VAR' L+121 and L+122, I found these values are zero.
