When I change an image, the other changes too, HELP! (.fla inside)

Hey guys, I am having a problem with my Flash file. Whenever I try to change an image, the other image changes as well. I want one image to stay the way it is, and another to be different, but it seems that if I try to change one image, both of them will be identical. How do I go about fixing this? I even tried renaming the instance names… I’m not sure.
I have attached a source file so you know more clearly what I am talking about. Just swap the image or movie clip with one of your own images and both of them will be the same for some reason.
