Why people assets not moving – only Biped Demo works

I’m currently working in Isaac Sim and I’m trying to use the People characters in a simulation scene.

The issue is that the Addett characters load correctly in the stage (mesh, skeleton, animation graph seem present), but they do not move during simulation.

The only character that moves correctly is the default Biped Demo.

Below are some documentation / example for how actor control works. If you still have questions/issues after reviewing them, please list down the steps to repro the issue (and error messages if any).
