Greetings, I've just imported my Aperture library into Lr 6 (using the Importer plugin) on a Mac. I've noticed that all the files now have an additional 5 numbers attached to the file name. For example, DSC_8261.JPG is now DSC_8261_32588.JPG. I'd prefer to keep my original file names. Any idea why this happened and how best to resolve?
