Columbus view, Clamp to ground, Cylinders Moving not clamped

I’m attempting to use Columbus view and make a cylinder clamped to ground with a height of 60 meters. For some reason my Cylinder’s move when moving the map. They even end up across the street. Can someone give me a quick code example to study to see where I’m going wrong at?

Hi @myjoegood, would you mind leaving a code example for what you have so far? Sandcastle is a helpful tool for sharing Cesium code examples.
