Why are you getting charged for Zones 1-4 when all you have used is
the tube in Zone 3 and the buses? A Zone 2-6 cap of £3.80 will apply
in this case.

Indeed. I belatedly realised my error. I tend to forget the Z2-6 cap
in exactly the same way as I tend to forget about the existence of a
Z2-6 travelcard.
