Energy annlysis for dynamo

I want to use this package (energy analysis for dynamo) to do energy analysis in Dynamo. However, when I use sample files to create energy model and set surface parameters, the system gives a warning.Revit is version 2018, Dynamo is version 2.0


why the result of PrepareEnergyModel.DecomposeZone node is empty? Thank you for your help!
