Why GoogleMapInfoWindow doesn't follow its marker's location?

When using google maps addon the the map information window is automatically put on the left corner, but not following with its marker.

    private void setMapMarker(Yard yard) {
        GoogleMapMarker marker = new GoogleMapMarker(
                yard.getName(), yard.getLatLon(), false);
        
        GoogleMapInfoWindow  gmiw = new GoogleMapInfoWindow() ;
        gmiw.setHeight("400px");
        gmiw.setWidth("400px");
        gmiw.setContent(yard.getOverview());
        
        OpenInfoWindowOnMarkerClickListener clickListener = new OpenInfoWindowOnMarkerClickListener(googleMap, marker, gmiw);
        googleMap.addMarkerClickListener(clickListener);
        
        marker.setAnimationEnabled(true);
        googleMap.addMarker(marker);
        

    }
