trying to assign unique bom id to parts but no text shows

Hi, I'm trying to create a BOM in composer but when I select the parts/assemblies from the top level assembly and assign a unique BOM id the part name and description won't show. these fields will show when I generate from selection however assemblies like the bearing have a lot of small parts and I only want to call out the top level assembly in the BOM. What am I missing
