Clamp to Ground Questions on Multiple Objects

Hi,

I have two entities safetyZone layer (geojson data) & asset (id 755337). We target only the safetyZone layer (geojson data) is highlighted with a red color but the red color is applied on both entities. A screen capture is attached. Any idea? Thanks.

  var tileset = new Cesium.Cesium3DTileset({
      name: 'CSCE Building',
      url: Cesium.IonResource.fromAssetId(755337),
    });
   viewer.scene.primitives.add(tileset);   

  
  var safetyZone = viewer.dataSources.add(
    Cesium.GeoJsonDataSource.load(
      "./qgis/safety_layers.geojson",
      {
        clampToGround: true,
        fill: Cesium.Color.PINK.withAlpha(0.9),      
      }  
    ),
  );
