Frontal view sticks while walking

I have a puppet with all 5 views. the walking is just fine. but when i add a swap set on different views(pic 1), when i try to walk it, the default frontal view sticks with the walking animation (pic2).

when i remove the swap set, the problem goes away. what i want to do is to walk properly and i can keep switching views from control panel. any idea how to solve it?
