Two circles ClipView problem

When I do

1) open this Attachment 119530 .xar file
2) select all
3) apply ClipView

... it will break. It renders some unexpected portion only.

I think I did something problematic to the yellow circle in advance, but I don't know. Actually I have created both shapes just by using the ellipse tool.

Clipview clips to the back image, if you want to clip to the large circle move it to the back, currently the moon shape is at the back.

Thanks! Sorry, I didn't know what I was doing.
