I am trying to update my keywording using PM/PM+ and Lightroom Classic (current versions of both on a M1 Mac with OS12.3.1). When I apply structured keywords via the structured keyword panel, sometimes they show up in Lightroom with the hierarchy intact. Other times it adds a keyword as a new flat keyword. I can't figure out why sometimes it does this and other times doesn't. I have attached some screen shots to show you what I have been seeing.This first one is the setup in PM.
I setup the structure in this cast so you have Editorial Image, Royalty, Sport and Travel as keywords They appear fine in the PM dialog box. Then on import into Lightroom the Editorial Image gets checked, as does Royalty, but travel (or anyother keyword) is made into a flat keyword at the bottom of the list in Lightroom (screenshot below). This happens intermittentally across the keywords Is there a setting or check box I am missing. I have tried turning off and on the use separator as well as the when updating XMP add structured keywords option in the preferences. Any help would be appreciated. Thanks Daniel.
