  I suspect a single unit is addressed 44B.  Which may well mean there is 44A, perhaps 44C and beyond.  Also, maybe 43B, 42B, and so on.
  I would have to view aerial imagery to guess if mapping every unit would be too much clutter (such as with tens of floors), for which I would treat this bugreport as a maps.me personal note on the public map.
