Now that I think back, I loaded the film holders while holding them long-edge horizontal, but on a vertical plane (i.e. pulling the dark slide out to the left). In that orientation, the notch was positioned "upper-right," but thoroughly backwards, which explains my error.
LOL ... I was actually very meticulous, just meticulously wrong (after all, I loaded all 20 sheets the same way).
VERY usable advice that will keep me from repeating my mistake.
