Why doesn't my divider wall behave like the outer walls of my shelf ceiling walls?

Hello,

 

I got some great help with the shelf ceiling but have not mastered it.  

 

I'd like the circled wall to be the same height as the wall with the arrow pointing to it.   https://1drv.ms/u/s!AonCBRorVv74rBeOi303s89xc0sU?e=roKUgp

I tossed in a wall break and while it fixed the wall height it left me this unusual construction racing stripe.

Not enough information to help.

Thanks - in the first post the plan is attached via the link.   I have two island rooms connected and the wall shared between the two stickes up higher than the shelf ceiling.   I'm trying to find out why that dividing wall sticks up.   I keep trying different ways of making it but don't seem to have a solution.   If I make one ceiling about an 1" taller than the other the dividing wall is the right height but when both rooms have the same height, the dividing wall sticks way up.

 

I can live with the 1" different but am curious why it sticks up if I make the ceilings the same height.

I don't know how it fixed it but I just got rid of the larger of the subdivided room  - redrew walls for it and it now has a level ceiling.
