One issue that developed is the pressure of the side rails (I guess) is causing the canopy frame to twist slightly. I am not sure if that is the problem or not. If you look at image one and two the skins "pucker" upward about .032" That gap did not exist until after I worked on the side rails. My guess is the whole frame is slightly too long and placing pressure on the forward frame. And this pressure is causing the frame to lift slightly causing the gap or pucker. Not sure but I will have to investigate next time.
