Duplicated shading surfaces

I got the following error of duplicated shading surfaces while modeling one detached surface with a hole as a PV surface. I’m not sure if it is caused by the trimmed surface in this case for which EnergyPlus may not be able to process.

It seems this shading surface is duplicated for 7 times, and there are only 3 vertices described for each surface in the IDF file where there should be 8:

The GH file of the simple model is attached here, and appreciate your kind advice.

Thanks.

@Grasshope ,
It looks like this results from a bug in @AntonSzilasi 's code for PV surfaces. Do you still get duplicate shading surface names when the shade surfaces are just EP context and not PV surfaces?
