There is a difference between XnView MP and XnView Classic:
editing IPTC/XMP data with XnView allows to only replace non empty fields, or all fields filled. XnView MP does only allow to replace empty fields. It would be nice to have some way to select what to replace.
MP / Classic: Editing IPTC/XMP: Replace empty fields

Re: MP / Classic: Editing IPTC/XMP: Replace empty fields
do you have changed the set IPTC settings (last tab)?
