Custom images are not displayed if IsClusteringEnabled = true

[alex-relov]

I set my image for pin, but in ios it is not displayed at all, and in android through time if IsClusteringEnabled = true

var p = new TKCustomMapPin
{
   Position = new Position(lat, lon),
   Title = $"Simulation Test {i}",
   Image = "pin.png",
   ID = i.ToString(),
};
list.Add(p);
map.Pins = list;

Black pin - is pin.png
