Problem of tracking entity with dynamic polygon hierarchy

Hi, everyone. I have a problem about tracking entity with dynamic polygon hierarchy. Here is the demos.

When I have a tracked entity without dynamic polygon hierarchy, it runs correctly.

Once I added the dynamic polygon hierarchy in the way of callback property, the tracking camera seemed to be still at the start moment that never tracking the entity.

Please help me!
