LDD help needed: Instructions Going Top to Bottom

[mouseketeer]

Hey everyone, I'm pretty new to LDD but this is an issue I've never come across before. I've built a building in LDD, but when I go to generate the building instructions HTML, they're constructing the building from the top down (first the roof, then placing bricks underneath until it gets down to the baseplate). Does anyone have an idea what's causing this and how to fix it? Thanks!
