Scan Stations disappear when panning or zooming

[sSeLeMaHs]

I tried to implement 360 Images from my Scan Stations like shown in the "360" example.

After a few challenges it works quite well, my Images are perfetly aligned with the pointcloud.

My big problem is that the Knobs representing my Scan Stations disappear as soon as i pann or zoom.

I implemented the following code:

async function run(){

		Potree.Images360Loader.load("./Bilder", viewer).then( images => {
			viewer.scene.add360Images(images);
		});

		viewer.mapView.showSources(false);
	}

As both the Images and the Pointcloud use the same local coordinate System, i dont need a transformation as in the example. But can i simply remove the transform part?
