"Double" Shed Roof Rendering Issue in Home Designer Suite

[Shnosh]

Hoping that someone will be my HERO and help me with getting the roof I am trying to create to correctly render!

Attached are 2 files: "Roof.plan" and "House Roof.png"

Although I can get a shed roof to render correctly with just a rectangle structure, I cannot with the porch/double-roof config I am going for with this design. I am sure that it has something to do with how I created the combination of railing and exterior walls, but I was not sure another way to draw my intention.

The PNG should describe exactly what I am looking for and has measurements but if you are willing to help and something is unclear, PLEASE ask! I will take typed instructions, someone editing the file for me, link to video instruction... ANYTHING. Tried working using ChatGPT, but it is not as good with Home Designer Suite as it is with some other things! Ha!

Thanks [in advance] to my "Hero"... now, fingers crossed this post finds them! :-)
