image to load in pointers

Using the following code, the images in the pointers are green with a black background instead of being red with a transparent background.

uses TeePng, TeePoin3;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Aspect.Orthogonal:=False;
  Chart1.Chart3DPercent:=100;
  Chart1.Aspect.Zoom:=70;
  Chart1.Legend.Hide;
  Chart1.Walls.Hide;

  with TPoint3DSeries(Chart1.AddSeries(TPoint3DSeries)) do
  begin
    FillSampleValues(5);
    Pointer.Size:=16;
    Pointer.Style:=psVisual;
    Pointer.Picture.LoadFromFile('F:\Downloads\Sensor.png');
  end;
end;
