I had the same question as you. I was reading on their website about this filter (ND8-ND2000) because I didn't understand if this filter is 9 stops why it has 11 marks plus 3 others marks for wide angle. So I found that the filter has to additional stops. The order is: nd8, 16, 32, 64, 100, 128, 256, 400, 512, 1024 or 1000, and 2048 or 2000 plus the other 3. So you should check if maybe you are not in the stop you are thinking. Maybe I'm wrong, but has been what I've found...I haven't use it because I just received it today.
