Looks like I just need to remove and replace walls until they all connect to make the room.

For some reason there were two walls on that side. I have deleted one and then the roof came back in line, but there is no bonus room now above garage. I see the walls on the second floor in the floor plan view and they look connected but it is not making a room.

Home Designer Pro 2019 I thought I had auto roof on. Now I have rebuilt the roof and it lowered it to the ceiling height but caused a weird blow up of one wall and the other roof areas. Sample attached.

Sorry, Attached is the plan. I am trying to reduce the height of the room over the garage. I have left the brick on the wall I am trying to reduce as red to show which one I am talking about. House Plan.plan

I have created a bonus room over a garage in Home Designer Pro. Following an article found in the knowledge base (https://www.homedesignersoftware.com/support/article/KB-00904/creating-a-bonus-room-above-a-garage.html) I created a new floor and set the wall height to 3 feet by setting the ceiling height to 3 feet. That turned out to be too much for the size of the garage under it and the roof pitch. I actually need the shorter walls (non gable walls) to be about 1 foot at the most. I will be putting shorter walls inside to create side closets. My problem is that now I cannot change the height of those walls. I change ceiling height to 12" in both room specification and in the defaults for the current room and then go back to room specification and set as default. Nothing changes. Am I missing something or do I just need to delete that floor and start over?
