Archipack addon is flipping my windows?

I have a question about the arichpack addon

When I create 4 walls… And then put a window in… the window is put in backwards. So the handle, is on the outside of the wall, in stead of the inside.

I know its the outside of the wall, because I give the "wall2outside’ material (that is automatically applied to a wall) a blue color in the viewport… So i know whats supposed to be the outside wall.

So its there anyway to flip the windows? Or am I doing something wrong?
