Are you sure there is a problem? If the flaps end up in the correct position
the motor run duration may simply be a part of the way things are designed.

Was this on the ground after landing, or in flight? I'd think that
the
air
load on extended flaps would help push them up in flight.

It was in flight. I'm not sure what the magnitudes of the airloads are.

Not answering the original question, I've noticed something recently with
my plane. It has electric flaps. It has two "notches", 15 degrees and
45 degrees, marked "take off" and "landing". When I'm on the ground
and set the flaps to "take off", the motor runs for a certain distance,
stops, but the flaps continue moving for a second and end up in the
correct position.

When I'm in flight, when I select the first notch, the motor runs for the
same distance but presumably because of the air loads, the flaps
stop there, i.e. no run on. This means the flaps aren't extended the
correct amount when set to 15 degrees in the air.

Apart from adding friction to the motor/mechanism so there's no run-on
on the ground, then re-adjusting for the correct position, is there any
way round this?
