Floor coming through the wall

[QualicoreHomes]

Hello again, 

Can someone help me out with explaining the reason why the floor is coming through this wall.  I tried all the options I know such as changing the framing to "stop at ceiling below" or "go through floor below" and "Balloon through ceiling above" but none work.  I also tried changing that portion of the wall by selecting "Lower wall type if split by butting roof" but I can not master it to have it disappear.  I looked on the forum to see if there was a similar problem but the best I can do is change the shape of the walls so the siding becomes drywall instead of siding but the floor edge keeps peeking through. 

Thanks in advance for your help!!

Looks to me as that must be a railing wall beside an open below room.  Not sure it should be a railing wall.  Post the plan and someone will figure it out.
