will PSE recognize the facial data (that LR 6 recognizes) and display them fully (names and rectangular face regions)
Thank you dj.
Is there anything that I can do in the image files to fix it?
If I'm working on the files in any case, I'll be able to do a little more and make them comply with both LR and PSE.
Fix what? This isn't broken, it can't be fixed.
The idea of sometime in the future of moving your face names from Lightroom to Photoshop Elements requires a "feature" that doesn't exist. In my opinion, you'd be better off planning to use Lightroom for the forseeable future, instead of planning to revert back to Photoshop Elements.
Fix what??? How the heck do you say that it isn't broken that a company, one that is a keypart of exif data boards, has two different photo management software that write metadata in incompatible ways without any justification for doing so? It is jaw-droppingly poor design and amazingly poor focus on their customers.
He is fully justified in the expectation that he should be able to switch back and forth as he needs and not have to worry. Coolaid drinkers on the other hand will justify anything a company does to them.
