Curve Editor and Translate Position Don't Match

I have a question about the curve editor and Edit Motion Layer Panel. I have a clip that I created where the character is dropping from Point A to B along the Z-Axis. I used the Edit Motion Layer panel to create the two keys for the drop with the intent that this clip would blend with my purchased Motion Clip. However the transition in and out of my clip needs to be edited. I went to the curve editor and under Layer Keys the FK BoneRoot position Z does not match that of the Translate Z position on the Edit Motion Layer. How do I access the Translate position and Rotate under Edit Motion Layer in the Curve Editor?

Very strange. I could not replicate that. It seems you are using multiple animation layers, which at some point were sampled. You probably have to walk back and try from clean slate without sampling anything. Apply motion and then at new animation layer apply the fall.
I would even suggest to make a fall with transform track as oppose to with motions.
