Hi there, I agree, not only the file names are not identical, which may indicate that they are not exactly the same files, but on two of them there is a difference that indicates that is a "bluesy" way of playing maybe the same set of notes. Well that is nothing new, there has been some Real Tracks with that distinction before (since 2011 or maybe 2010 version). So yes, I wouldn't erase them at all.
