Material sbar importing issues

Hey guys, I am having an issue I can't figure out.

I have made a material with Substance Designer 5.

Inside SD it looks just the way I want. But when I import it into (5.3.4 and 5.4 beta). The roughness isn't getting saved.

I ticked Generate all outputs, which creates the roughness map, however - it doesn't do anything no matter what option I selected (Roughness,Specular,Opacity,etc,etc).

So I then just drag and drop the Roughness texture into the Specular Map slot, and then it just makes my material the color of the roughness map (Black and White).

So if I don't have a roughness map, then the entire material has a constant roughness over everything.

Here's how it looks in Substance Designer.

Heres the Unity Material.
