Reset Transition not reseting default "Transition Duration" value.

repro:
Import attached package
open Set-up scene
select mangagirl and add 2 clips to her controller
create a Transition between the 2 clips
(note that the "Transition Duration" value is 0.25 by default)
select the transition and change the "Transition Duration" value (ex: 0.5)
now select the "reset" option in the pull-down of the Inspector...
result: "Transition Duration" value is set to 0.1
expected result: "Transition Duration" value should be reset to 0.25
