Puppet waist, during walk cycle, is doing something odd.

I have been working on creating some puppets with Illustrator and CA. 

I recently watched this puppet walking video from Okay Samurai, and attempted to do this with some illustrator puppets I created.   

I noticed the waist on my puppet was larger than needed after watching the run & sneak styles. 

I opened the file in Illustrator, deleted some anchors on the waist shape, saved AI file, back to CA.

Now the waist looks like it is doing some odd behavior, but there are no behaviors added to the waist or body layer. 

The anchors at the bottom center of the waist stay in the same position, while the rest of the waist moves with the body in motion to the walk styles.

Any suggestions, insights, recommendations are appreciated.

Thank you!
