There is nothing wrong with your settings. PM just doesn't delve as deeply into DNG files as it does from photos generated by an actual Nikon camera.
Thanks for getting back to me. Any chance that PM could delve deeper into DNG files as well, or would it be very complicated to add that functionality?
Yes it is possible that a future version of PM could parse DNG files more deeply.

Please add this to the feature requests - more info from the DNG files metadata. ;-)
