Hi!

You've set the residential areas in Wareham to residential=urban.  According to https://wiki.openstreetmap.org/wiki/Tag:residential=urban?uselang=en-GB and https://wiki.openstreetmap.org/wiki/Key:residential this is for areas with blocks of flats - Wareham has very few of these (e.g. I can think of one in Northport).  Depending on the area, residential=terrace/duplex/single_family/detached might be better.
