This past week I shot some photos using my Canon EOS R5 and my DJI Mavic 2. I imported all photos to Lightroom on my iPad and sync'd them to Lightroom Classic on my Mac through the creative cloud. When I got home I inserted my memory cards and opened the import window to verify all photos truely sync'd. When I checked the card from my R5 it showed no new photos. Then I tried the card from my Mavic 2 and it showed all the photos taken as new photos in the import window. I selected import then checked after the import was complete and the newly imported photos imported as filename-2.dng. So these photos had been sync'd but for some reason Lightroom Classic didnt recognize them as duplicates. When I look at the metadata everything is the same for filename.dng and filename-2.dng. Again this issue only happens with the Mavic 2 photos and not the R5 photos.
