Tagging Generic Elements in IFC files

I loaded the IFC Revit model that is automatically created when inserting an IFC file. I tagged elements from the wall panel IFC link using the IfcName parameter for direct shapes. I inserted a second Revit file made from a roof truss IFC model. I can’t tag the truss elements which Revit considers generic models. They have identification in the IfcName parameter but the tag only shows question mark. I made sure the tag is using the IfcName parameter for generic model. The tag won’t gather the parameter in the IFC Revit model either. I’m attaching the tag family and the IFC model, both in Revit 2025.
