Nikon N70 film camera ghosting pictures?

I've just been experimenting with this camera. I lost the manual and found an old one online. Every once in awhile it will ghost my pictures and I was just trying to figure out which setting in the variable program is doing that or if its something else.

Ghost = 2 exposures on the same image. That means that either the film transport is not working or you got it set to double exposure.
