Pset_ProvisionForVoid twice in IFC - How to avoid this behaviour when exporting from Revit.

I did an IFC export from R24 for a ProvisionForVoid model. I imported parameters from the 'IFC Shared Parameters-RevitIFCBuiltIn_ALL.txt' file (only Shape & System). Then exported the file using a UserDefinedPropertySets text file.

I ended up with two identical PropertySets in the IFC, as shown in the picture from Solibri. Blender on the other hand combines the two propertysets. Is it posible to export a more pure IFC from Revit where I don't get duplicate Psets and duplicate data in the IFC file?

    ## IFC file:

        #12680=IFCPROPERTYSINGLEVALUE('Height',$,IFCLENGTHMEASURE(1500.),$);
