Isaac Sim quadruped example

Hi, I am using Isaac Sim 4.2.0. When I clicked the example->quadruped as Quadruped — Omniverse Robotics documentation, the spot(policy control) can move correctly through keywords twist, but for Unitree A1(QPController) it can only walk in place. Do you have any ideas? Thanks!

Sorry, keyboard not keyword

Please outline the specific steps needed to reproduce the issue in detail.
