need Zero2000 help

Hi all. I just picked up the contact sheet from my first attempt at pinhole photography, with my Zero2000. Overall, I was pleased, but I had a problem with part of the roll in that the film seems to have been anything but flat for some of the exposures. Most have a slight bit of rounding in one corner that I could live with, but in 3 the image has a very noticeable roll or ripple across the bottom and top of the neg. The film was obviously quite un-flat for these exposures.

Any thoughts on how to remedy this. I thought about installing a second spring clip in the camera on the fresh film spool, like that used to maintain tension on the take-up spool. The problem with that would be having the film too tight and dragging the emulsion across the baffles inside the camera. Another though would be to build up the camera back on the inside with some kind of material, essentially installing a pressure plate.

Any comments would be appreciated.
