SwapDepths Movieclips won't LEAVE!

Ok SwapDepths can be a wonderful thing…but in my case its proving to be rather annoying. I have a button which calls a big movieclip. Inside this movieclip are 3 other sub-clips arranged in a folder-tab like order which swapDepths when you click the appropriate headers. When you close the main clip and move on in the timeline the movieclips stay put, much to my frustration.

Is there any way to stop this from happening? Is there a way you can return the movieclips to their default depths so they don’t stay on the screen when you move the timeline along?

Thanks to anyone who can help me!
