I had exactly the same problem. The problem is that with DNG files,
the tags are written in the DNG file. DNG files do not use the XMPs,
some software do, some don't.

I ended up remove the tags from the DNG with exiftool.

to see the tags in the dng:

exiftool -G1 -a -s -IPTC:Keywords -XMP-dc:Subject -XMP-lr:HierarchicalSubject FILENAME.DNG

to delete the tag in the dng:

exiftool -IPTC:keywords="" -XMP-dc:Subject="" -XMP-lr:HierarchicalSubject="" FILENAME.DNG

then 

1. re-read the file in DK
2. cleanup your tags/categories
