Do you these properties added in the standard components?
The smart fasteners probably don't have the same custom values as your parts.
The CP for Description is probably description, double click to find out.
Check your Custom/Conf.Spec properties to figure out what Description says.
The Part Number is probably defined in the configuration properties in the part file.
The Description may be as well if "Use in BOM" is checked. This will overwrite whatever is in the Summary Info section.
