    It's really not clear from that document the exact problem that you're having or if you've already solved it. What I do notice is that Loft 1 seems like it should have been a simple extrude, either up to a surface, or split by a surface. There's a lot of complexity where you probably don't need/want it.

    Looking at the end of Loft 1, it seems like it could have just been extruded:


    Then, looking at the curvature analysis/combs you can see that the surfaces are getting close to being degenerate (3 or 2 sided, instead of 4 sided). This will likely lead to downstream weirdness.
