I posted this question on Saturday, but can't find it? When I use "Edit in" to take a photo from Lightroom to Photoshop, the photo returns to Lightroom with the keyword not under its proper place in the hierarchy, but as an individual keyword. So I have to add it back to its proper mother keyword, and then delete the orphaned keyword. Belowis my keywork list with the main categories in all caps. The random subcategores that are not capitalized (Like "blackbear" which should be in the ANIMALS main file) are the ones that have been edited in Photoshop and are returned to Lightroom not under the main keyword. Help!
Did you perhaps use 'Save as' in Photoshop to give the image another name? Lightroom expects the image to return with the same name, and so you must use 'Save', not 'Save as'. In the past, using 'Save as' would simply not return the image to Lightroom at all, but that has now changed. Now the image does return to Photoshop in that case, but it might be handled as a newly imported image and if you import an image with embedded keywords then this may happen because the embedded keywords do not have the Lightroom hierarchy.
