Modified radiation data in epw file for radiation simulation but failed

I have replaced the direct and scattered radiation data in the epw file to get a new epw file. I simulated radiation with genCumSky in HB-legacy. But I found that the weather file data used for the simulation is still the data of the original epw file. I would like to ask where is the problem.

Fill in the missing data. However, the radiation data at this moment in the simulation is based on zero.
