Hello PX4 community,  
I am using the PX4 software and testing the terrain following feature both in simulation and on a real vehicle. Even though I set the required parameters, when I run the system, the vehicle does not follow the terrain and only flies at a fixed altitude

**The hardware and software I am using are as follows:**

- PX4 Autopilot Software: 1.16
- Holybro Pixhawk 6C Mini
- In the simulation environment, I am using `gz_x500_lidar_down`.

More detailed information, the parameters I set, and the flight review files can be found on [this](https://github.com/PX4/PX4-Autopilot/issues/25423) page.
