Ok, so the way I do my workflow (which I realize now needs fixed), is to import from my camera into DNG's. Then I edit the folder to my liking (all in color) and export into a brand new folder as .jpg's. From there I make the entire folder of edited color photos into Black and White and export as a copy with a new name, so I've got a color and a Black and White version of the photos in the same folder. In my finder window I see the color and the Black and White versions, in their perspective Color and BW, but after I synchronize the folder in LR, it shows all the photos (2 of each photo) in Black and White Only? What is happening? (and no nothing is checked in my import options)
How are you applying the B&W? In LR, Camera Raw, or Photoshop? If applying them in ACR, do you import the metadata from file when in LR?
