not repro in 5.2

Repro:
Add attached Interpolations.fbx to project.
Drop Interpolations asset into scene.
Grab "Take 001" clip under Interpolations, and drop it onto Interpolations GO in the scene.
Select "Stepped : Position" transform and step frame by frame through frame 30 to see the Stepped GO takes 2 frames to step from previous to next value... should only take 1 frame.
frame 29 = good
frame 30 = bad, only half value
frame 31 = good

notes:
This only happens when "importing" constant cuves, created constant curves are fine. This happens on any transform, not only rotations. This happens regardless of the "Resample Rotation" import option.
