Guild Wars 2

I have tried to make make different insignias and shoulder components, but nothing seems to work. All the other sets have pieces going Seeker, Outlaw, Leather, Rascal, Prowler etc up though the levels. But, I can’t seem to find out how to make the shoulders in the leather set.
Am I missing something or is it intended to not be there?

shoulders are on the bottom but you have to set up it’s recipie in the discovery section
you take the puldron pading the leather exterior and an insignia and put them into the discovery pannel. after words you can then fully craft them on the fly.

I know how the discovery works. It is just that I have tried to make different kind of shoulder pads and insignias, but so far nothing has made shoulders called Leather, like all the other items in the set.
All the other items in the set uses components called Coarse (created with wool and coarse leather, and cotton insignias. However, if I create coarse shoulder paddings and such and puts it together with a cotton insignia, it creates Outlaw shoulders. And right now, both thin and coarse seems to be creating Outlaw shoulders, while Thin components on the other parts creates Outlaw and Coarse creates Leather.

Hm, maybe it is just named wrong? Since the Outlaw shoulders created with Thin components have another look than the Outlaw shoulders with Coarse components. I noticed that now. That all my shoulders with Coarse and cotton insignias have one look, and the Thin with wool insignias have another.
