Puppet warps during walk

I have Left, Front, Right, Rear profiles. I have the Walk behavior on the topmost layer like the Walkbot example. The Left Profile was finally walking ok, still needed some adjustments, but at least the knees were bending correctly and arms swinging at the shoulder. Right was warping. So I compared the two; they both looked pretty much the same but I made some changes to the Right to further match the Left. Now, the Right is better, but the Left is totally messed up.
Also when I go back to the Scene, he disappears. I have to hit the keyboard trigger to make him appear.
Looks like the Tags are contradicting each other or something.
Here's my puppet: JERKVILLE.puppet - Google Drive
I really want to start the animation but seems like I've been trying to rig this guy for weeks now. Help? thx
