Porch/deck with gable & railing wall with post to ceiling penetrates roof.

[RickyBobby]

What I'd like is for the posts to stop at the roof line. Here is the small example of my larger plan. There is one room(porch) with two roofs and each has their own wall(I broke the wall) just for this example. One does not penetrate and you can see how the other does. Both "balloon through the ceiling' bc I want the posts to go to the roof line. With one railing wall all post penetrate the roof. Is this a fault of my version? See test plan
