I am trying to use structured keywords to add to existing keyword hierarchies in DNG files.
If I have a file that has an existing hierarchy as written by Lr, that shows in PM as both a flat list of keywords (US, CA, LA) and as a hierarchy (US | CA | LA). If I try to add the structure "animal | mammal | wolf" it fails; nothing shows up subquently in Lr.
If, however, I delete the flat list (US, CA, LA) then Lr does write the hierarchies, both old and new, appropriately.
Needless to say, I don't wanna have to manually delete the flat list every time I add to the hierarchies that exist. Am I doing something wrong?
EDIT: turning off the option to only write structured keywords to hierarchical keywords, and just appending the "|" piped list to existing keywords, seems to work better, but seems counterintuitive. So I'm still at a bit of a loss.
