I am sorry but I don't understand your problem. Please try and explain a little more. All I can guess at is that you added seven pre-comps to a timeline and that something went wrong with the render.
A screenshot that shows all of the layers in question with properties revealed and a view of your comp window would help. It looks like you are getting nothing but a gradient background. I'm not sure what layer that is.
Try using solo to isolate layers and make sure that you are looking at the active camera in the Composition Panel.
