I believe that the footprints represented by WAY: 1306868118 & WAY: 1306868117 (flagged) should be smaller and circular; not 'tic tacs'. The shadows cast by these buildings do appear to originate from the edges of the footprints you added, there is a colour difference between the east and west part of the features, and the imagery is off-nadir making the north and east walls of buildings visible in the imagery used to digitize them. If you wish to view my modifications you can do so via the way's history. I hope this is helpful.
