I can't reproduce here with the development version of digiKam-8.0.0. The tag is only added once. How are your sidecar settings? Please update to the currently stable digiKam-7.8.0 version.

You have duplicate the person tag outside of people, when this is added it appears duplicated. Ok, for DC and IPTC it's weird as a single keyword.

Comment 4 José Oliver-Didier 2022-09-17 13:40:48 UTC 
This should also apply to the EXIF XPKeywords as well not just dc.subject and iptc keywords.
Comment 5 Maik Qualmann 2022-09-17 15:17:07 UTC 
The metadata entry EXIF XPKeywords is currently only readable for us with Exiv2. It's a long story, bug reports exist.
