I'm using FRV to take a quick look at the photos (I've already imported into Lightroom) in order to select and rate and label them. But LR doesn't seem to find all the metadata conflicts! E.g., I've got 101 photos labeled red and 42 starred in FRV, but LR only has 62 red and 16 starred. I tried restarting the software, but nothing changes. How can I force LR to recognize the changes???
