People and face region metadata being stripped/not copied on save or export

[Curtisb]

Apologize if this is know/expected but I could not find anything about these fields in my searching. 

Took me a long time to figure out what is happening with my people/face tags that were randomly missing but it turns out it wasn't random, it was jpg files I had edited with Affinity after tagging.  I've attached shot of a 'person' before and after a quick edit with Affinity and a Save.   Both the face region and the people tag is missing after the save.  Same thing happens with an export. 
Some of the affected fields are "region Person Display Name" "Region Name" " Region Type" and Region Rectangle

(I tried to attach the original documents but it keeps inserting images into the body of the fields, so let me know what I should include/export to help highlight the issue if it is not already known).

Welcome to the Serif Affinity forums.

To attach your original files here, you should first zip them so the forum software doesn't interfere while optimizing them for display. Then attach the .zip file, instead of attaching the .jpg file itself.

Thank you.  I've attached the images and EXIF data in txt file for the original and for a second example.

it looks like the info is there just rearranged slightly - not sure why windows isn't displaying it
