In the middle of creating a DB of faces I discover that many identical copies of a pic that I've designated as a particular person keep coming up requesting to be labeled. I have numerous dupes and why on the 3rd instance of the same photo I have to tell LRC who that photo is of is beyond me. Then, the 35 people or so I've grouped the images into spontaneously turn into a dozen people. Most of these people are the sides of buildings and other non-human images. Please advise.
