Where are LLDP and CDP categories set?

I have some devices that I expected to pick up the LLDP Neighbors and/or CDP Neighbors datasources, but those require LLDP and/or CDP categories, but I'm not sure which part of LM would make that assignment. I dont see any property sources specific to LLDP or CDP, and I dont usually get too deep into the weeds on debugging category code.

Any suggestions on which property source this comes from, or if its from sysoid maps or something else?

Thanks!
