Lightroom 5.6: HierarchicalSubject tag in jpegs - when modified externally, Lr no like. (xmp sidecars: aok).

I'm trying to do an xmp based sync (using exiftool), but running into a problem:

it works fine for xmp in sidecars, but not for xmp embedded in jpegs.

I mean, most tags work fine - all so far, except HierarchicalSubject.

Example: if metadata changed in Lightroom (note: down arrow), then hierachicalsubject tag changed externally (expect: conflict flag, as for other tag changes), the down arrow persists. If forcibly reading metadata (via Metadata menu), it looks like it's working (progress scope advances..), but the down arrow persists and the metadata in Lr (structured keywords) does not change.

Repeating exact same procedure except xmp as sidecar to raw - works perfect, as expected.. (metadata flags behave appropriately, externally changed keywords take effect..).

OK, I figured it out - need to attend to 'Subject' field as well as 'HierarchicalSubject' field, when jpeg (DNG too?).

Still, I would expect it to work same when xmp embedded in jpegs as when xmp in sidecar, but it doesn't..
