ArcGIS Feature Layer with Callouts not working properly

I have one map document with the same layer added three times, each layer has a different color symbol. I published the map as a map service on our server. In my app I call each layer from the map service separately, each as ArcGIS Feature Layers.

When I open the map all three ArcGIS Feature layers appear.

Next, I have a callout set-up in my app. When you click on a point from one of the feature layers the callout is suppose to appear for each of the three feature layers, BUT the callout only appears for one of them.

The reason I set-up the app this way is because I initially had one ArcGIS feature layer with a callout and everything worked fine. Then, I needed to be able to turn different colored dots off, so thats when I went back and added the same layer three times with different colored dots for each in my published map document, then I called those layers separately in my app, now only one of the layers callouts work.

Only callouts for flayer are working.

Java Code:
public class Mapscreen extends Activity {

 public MapView map;  
  
 //Callout Variables
 private int m_calloutStyle;
 private Callout m_callout;
 private ViewGroup calloutContent;

 ArcGISFeatureLayer fLayer2;
 ImageView CallOutClose;

  // Get basemaps
  basemapTopo = new ArcGISTiledMapServiceLayer(this.getResources().getString(R.string.WORLD_TOPO_MAP));
    
  // Add basemaps
  map.addLayer(basemapTopo); 
  
  // Get feature layer = Blue = No
