Trip Planner | "Could not create Waypoint" when attempting to add destination that is YELP

I don't have an explanation other than some Yelp search result items will add as waypoints and some won't (eg:  Littlerock Grill won't but Angelinos Wood Fired Pizza in LA will).  This oddity was posted about on the BaseCamp for Mac forum 7 years ago without an explanation.  The BaseCamp notice says something about "licensing restrictions".  Perhap it costs $$$ for the facility to include coordinates in the Yelp database.

A workaround is to copy the address from the Yelp popup, search for it, select that address from the "Addresses" section of the search results and add it as a waypoint, edit the waypoint adding the facility name, icon, etc.
