Dear,
I'm getting the folloeing issue when I export my model from Revit 2019.2 to ifc. When I want to export a Property set with muy custom parameter, which it's in the family like a type parameter, the export pluggin duplicate the PSet with the parameter and data within.
Find pics below and test files:
Family with family's parameter type
