Problem with a wall

[MN_JohnH]

I have a wall here I can not figure out. It is mostly an interior wall that has portions that are on the exterior to be a different type than below the roof.
But the side that the siding need to be on is opposite on each end. But I don't think that is the problem necessarily, for some reason it builds as an interior 6 above roof even though it is set as a siding wall to have interior 6 below..
Why doesn't it build up into the high gable? I mirror copied it from the other similar wall and that other wall seems to be working fine.
Why is the exterior portion above the roof still Sheetrock?
What is going on in that inside interior corner where there is some siding showing?
The interesting thing is, I rebuilt it and it all looked great till I closed it and reopened it again, then this problem still persists.
The only difference between the two walls that  I can see is this wall that I am having the extra trouble with does not carry down to the main floor.
That is intentional, that is going to be open on the main level, this wall is just on the second level.  
I have a picture here that sort of shows the issues. It's a large file so I have it in a drop box here: https://www.dropbox.com/scl/fi/gsypb3i6xyxmsv482lell/Complete-rebuild-8-15-25.plan?rlkey=vunr5v60zq4ybo9o3xmnx9rsy&st=pamirn5y&dl=0

When you open up the DBX for those walls what is the pony wall set to? Something might be out of sorts there. Another thing I would do is move the wall perpendicular to the roof to see if the wall behavior changes. The wall is acting on some directive you just gotta figure out what.

Thanks, The pony wall is set to the interior wall type, that happens automatically apparently when you check the box "lower wall type if split by butting roof" . Maybe that is not what I want, I guess I could just keep it as in interior walls and use wall material regions for the siding.
I found I had a ceiling height in one of the rooms that was causing the wall not to build up into the peak, (even though no flat ceiling over this room was checked).
So I guess I will forget the different wall types above and below the roof and set it to interior and the I can put the thicker sheathing and siding as a material regions on the exterior.

It should have your siding above the roof on the outside and drywall below on the inside. Unless I am missing something. Maybe if you posted your plan I could have a look.

The plan is over 80 mb. I spent a bunch of time trying to strip it down and got down to about 40mb, still way to big. That's why I put it in a drop box to share with the original post. It was the only option I could come up with.Yes, the wall should show siding above and drywall inside the house below the roof. That is really the core of my question, why this is not working.
Thanks for your time looking at this and responding.

I see that now. I have X16 so I can't open anyway. ugg.

You have to split the wall using the Add Break tool, and reverse the interior/exterior direction:

I simply went to the Attic layer and added an attic wall.

Pull the roof planes over to snap to the wall:

 

 

 

You've got some other issues to do with spraying the wall material (not advised), among other stuff, but that's as far as I took it. Get that stuff fixed then let us know if you still have other problems.

I was able to strip the file down to 21 MB and zip it to under 4 MB. Do this in the future, it makes it much faster and easier for others to troubleshoot your issue.
