After baking, I lose all my material controls

Hi,

I am very very new to Substance Painter, so I am probably missing something obvious but I'm totally stuck.

After exporting my FBX from Blender, I followed this tutorial to bake all the maps I needed.

When I finish baking, I have no controls for HSV, tiling, scale, height, etc. Usually there are some things I can tweak, but now it just shows all these maps and those weird L8 and L16F things

.

How can I get controls back? I want to add materials and change their scale & hue, and am hoping there's a simple way I can do this.

Thanks so much.
