This only happens with the 2509n reel? Not the B's insert? Do you load the film with the notches first? How many sheets at the same time, and does it affect them all?
Looking at my 2509n reel, I am at a loss as to what could cause those marks, unless the film is not slid all the way in to the end. Even then I cannot account for the curved motion of one of the marks. If the paddles are used properly, the film is not going to move. I suppose that doing inversion with insufficient solution might cause the film to flex that much - but I can't see that happening with six sheets loaded and a normal slow inversion. I only do rotation with my Jobo 2500 series tanks.
I do wonder if the film is properly loaded in the holder. The curved mark could be caused by the darkslide hitting film that was not in the guide slot, and the heavy dark marks at the flap end could be from the corners of the darkslide hitting the film. I can't see this happening exactly the same way every time, though.
