The whole table contains empty rows, whereas that for X3 contains details such as X-Resolution and Y-Resolution and usual EXIF data such as Exposure Time.
I think this is why the likes of Norm (Yukoner) is not seeing the correct Resolution.
Norm, where are you seeing the Resolution (dpi aka ppi)?
If you use Edit Mode Image Information it is correct but if you use the Manage Mode or Organizer I suspect it defaults to 72.
