People tags do not survive an edit

I select a file which has people tags associated with it.

I do any edit using PE editor

I save with a different name

Go back to organiser

The edited file is not shown at top of all media

find it using file name

NONE OF THE PEOPLE TAGS THAT WERE ATTACHED TO THE FILE BEFORE EDITING ARE ATTACHED TO THE EDITED FILE

I first posted this query in December 2017. No-one came up with any help.

I have just finished a chat with an Adobe person who says I should try again.

He promised that it would be answered.
