Sorry man, I can't fix that problem. However as EXShadow said, you can fix it by setting your layer number to "2" (layerno = 2) for your life bars...if you know a bit of programming.
It's strange, I can't reproduce that problem...So I have no idea how to fix it.
Anyways I've updated the stage. Maybe that'll get rid of the problem.
