how to delete the mask cause by pupppet pin?

Hi! I'm new to AE, and I have some trouble using the puppet pin tool. I was trying to make the object bend while rotating. However, the pins don't move with the object and there was a mask that will block over the object. I wonder how can I deal with the problem. I attach the screen recording down below. Thank you.

Layers with Puppet Pin animations have any transform animations (position, scale, rotation, anchor point) after the mesh has been created. The mesh is created as soon as you add the second pin it does not move with the layer. It is fixed. It renders before Transformations.

If you need to animate the Puppet Pin layer, there are two options. The first is to add the Transform effect after you add Puppet Pin. The second is to pre-compose the layer, making sure you move all attributes to the new composition. Several effects behave in the same manner. Pre-composing changes the render order so that the movement is applied after the effects are. 

If you are ever confused by render order, just expand the layer in the timeline. Masks are first, then Effects, then Transformations. Layers also render from the top down.
