Tailoring problem

What could be the problem is no one has learned from my recipes: 2 blue Spellthread leg enchant and all Embroidery back enchants. (Tailoring)
Im skill 438, the recipes mentioned above 420 kill need.
I also learned them. I checked it Dalaran Master Tailoring Traner and all recipe gray.
I can't find it anywhere among my learned recipes, I've checked it several times.
none of the tabs are closed.
In the Gm ticket, he asked for pictures of the problem. I took several pictures of it, but how and where can I upload it?
