You have two different DMW keywords - one at the toplevel of your hierarchie of keywords, and one DMW as a subcategory of "iPhoto". When you imported iPhoto, probably that keyworrd was created automatically.
You can merge these two keywords from the keywords HUD. Then the iPhoto version will be merged into the toplevel DMW keyword.
- Launch the Keywords HUD by typing ⇧H (or "Window > Show Keywords HUD").
- When the HUD opens enter DMW into the search field.
Now you will see two instances of DMW.
Drag the lower DMW down to the bottom of the HUD to move it to the toplevel.
Now you should see a warning.
Press "Merge Keywords".
All your DMW tagged photos will now have the same DMW tag.
Alternately you could delete the DMW(iPhoto) keyword using the delete button at the footer of the HUD. That will remove it from the photos.
You are welcome, Douglas.
Yes, I have to fix duplicate keywords more often than I like, when moving photos between iPhoto and Aperture.
I see, you could figure it out, even with the ASC forum software messing up our screenshots.
I meant to post this as the second photo, but appently the forum software did not like it:
