Check the IFC in an IFC viewer. What IfcClass is it there? Your problem most likely is that the export or import mapping tables aren't set correctly (I'd check the import first).
To check the export table go to For export go to R > Export > Options > IFC Options. Find the IfcClass your element is supposed to be in and see if the correct import Category is set. For import go to R > Import > Ifc Settings and do the same.
By the way: you can modify these files for your need and save them.
