Multiple xmp face rectangle tags are displayed OK with -struct but look wrong if flat.

Tested with the attached 1940.jpg (has several family members named).
The output is OK with
exiftool -struct -xmp:all 1940.jpg
The output looks wrong with
exiftool  -xmp:all 1940.jpg

The erroneous display (with repeated names and the (100%) added to some names) appears to mimic the problem that Picasa randomly introduces into face tags, so I suspect that Picasa is somehow using the exiftool flattened output to manage its face rectangle tags. The tags in the file were created from my Picasa data using  Andreas Vogel's (wonderful) AvPicFaceXmpTagger program.

I am a newbie, and apologize if this is all due to my error.

This looks correct to me.  The flattened output is difficult to interpret for lists of structures like this, but it would make more sense if you use a different separator, i.e.)

I can't comment on why the file contains duplicate names or the "(100%)" after one name, but exiftool is just reporting the information from the file.  Here is the raw XMP:

In this case, the raw XMP is somewhat more readable than the normal ExifTool output.  But for readability, perhaps the JSON output is best in cases like this:
