Unity 5: Apply Root Motion not affecting "Y" in 2d

I used the new unity 5 feature to "Generated Root Motion Curves". Then I hit "play" and triggered the animation. The character in the X axis, but not the Y axis. Next, I clicked "Debug" saw that "Keep Original Y" checkbox was set. I unchecked it. I played the animation again in-game. No change. Halp. This is a 2d sidescroller project. I am trying to make an NPC "pull" itself up from a ledge hang. Looks great in Scene preview. Doesn't work in-game. X only movement means he pulls into the wall then falls. This NPC has no collision enabled.
