Question: I used a tube with closed ends to construct a hanger with a ridge on the roof. when I moved a point below the level of two adjacent points, the end got confused. Is this a bug or am I trying to do something that I shouldn't do?
So, I made a "worst case" example
Notice how the ends do not follow the shape.

The problem is that FSDS - nor FS for that matter - cannot handle concave polygons. The end of your part is high, then low, then high again, then low again. FS and DirectX aren't sure how to draw this mostly due to the drawing order of the points.
|1. Delete the end polygons of the part.|
4. Repeat step 3 for image3 and image4.
5. Repeat for the reverse side of the part.
