Layer issues with duplicated MCs

Hi, I’m a new member, but since I know you’re all busy people, I’ll just get to the point ^^

When I created duplicated MCs of one thing, they unfortunatly do not go underneath objects in a higher layer. The original MC will go underneath it, but the new clips won’t… I’ve done all the AS in the same layer as that original MC and tried fiddling around with various things to no avail. I’m still fairly new to Flash and am unclear as to why this is happening. Can anyone help me out here?
