BLE TagOverride in room-assistant

I am using beacons to track my cars, first with monitor, now with room-assistant. I’m trying to use the tagOverride configuration parameters to give the trackers reasonable friendly names, but it’s not working - still get the UUID for the entity id, and the friendly name. Please see my configuration below; are my expectations correct, and is this configured correctly?

(room assistant 2.17.0, on a pi zero)

Thanks for any help.
