There has to be a logical cause.
You need to try & match the line on the film to the position in the back, and the camera without the back. I assume you've checked the pressure plate.
It's highly unlikely to be a light leak, but at this stage it can't be ruled out, try a bit of tape over the dark-slide slot, I'd expect heavy fogging though at one point on each affected frame.
There must be someone near you with an ETRS, ideally you need to try a different back & see if that eliminates the problem, also try and get another user to have a good look at it. It must be extremely frustrating
