Wall problem at roof

What is wrong with this gable wall? 
I just want it to carry all the way across and be interior below the roof and exterior above the roof and I get this.

That wall is being cut by a roof plane on the 2nd floor.

Pull that small section back to butt against the exterior wall and your wall should then build correctly.

Also, set the ceiling elevation in the hallway back to the default height. Because it doesn't have a flat ceiling, there's no need to alter the ceiling height.

Split that gable wall at the lower roof peak and change the wall type for the portion at the top of your screen to be an interior wall type.

Then, set the gable wall to balloon through the ceiling above.

Thanks for all that. I didn't notice that little part of the roof sticking in there. But it seemed to be the ceiling height that really solved the issue. Dang, I don't think I would have figured that out.
