Why is my "Advanced Armors" perk not working?

As you can see in this first screenshot, I have the advanced armors perk.

Advanced Armors

And as you can see from this second screenshot, I can't craft neither scaled nor plate armor. What am I doing wrong?

No Scaled or Plate Options

As added notes in case it helps, I'm playing on PC and I added the advanced armors perk to my character through the console.


Scaled and Plate armor will show up under the existing category Steel, as they do not require their own materials.
