Issues with Transform (Rotation)

So I've built a couple puppets in Illustrator and imported them into Character Animator; the blue puppet is permanently in right profile, and at certain points in the animation, I've used Transform to rotate her head so she looks upward or downward - I found this just worked better for my purposes than using Head Turner behaviors.  You can see the Rotation keyframes in the screenshot (for the blue puppet.)   

When I manually drag the current-time indicator over the keyframes, I can see her head rotates up and down nicely-- I've added dangle physics to her hair, and I can see that moves as well.  But when I actually hit play or record, her head doesn't move at all, like the keyframes aren't there.  At best, it rotates down slightly and just freezes there for the rest of the scene. It doesn't rotate in After Effects where I've linked the scene, either. 

The frustrating part is, I've done the exact same thing with the purple puppet, and his head rotates just fine!  Every keyframe shows up when I hit play. I've used all the same settings with him.   

I can give more info if needed, and any help at all is appreciated. Has anyone else had a similar issue?
