Hi there! I've been banging my head the whole afternoon trying to map these two fellas from my Revit file into the IFC. Basically they don't show up in the IFC's Property Set after export. When I export the file with the Revit PSets, then the attributes show up in their PSet with the same names as in Revit: Assembly Code and Assembly Description.
I have no idea of what can be wrong. I couldn't find if the attributes have another name on the backend of Revit, like Type, that sometimes is Type and others Type Name. Does someone here have an idea about what can be wrong here?

In case somebody wonders, here is the mapping table of the RVT Categories to IFC Classes:

Thanks in advance for the help!
