Export SWF Layer problem

I have a animated character that has roughly 35 layers and when i export it to SWF a couple of layers are invisible. If i import the SWF in Adobe Flash Professional it is the same thing but i can see that the layers that are not visible are actually there in the list of symbols and layers in the animation frames.

If i remove visibility of a couple of other layers the layers that are missing pops up so i am wondering what ToonBoom is doing to destroy my exports?

Sounds like the layers might be hidden or displaced. Have you tried selecting the layers and looking at their placement in the top or side view windows?
