An easy way to check and make sure it's learned is to take your crafter to the Psijic vendor and see if it says recipe known on the recipe. You can see that without needing to repurchase the recipe.
Did you uncheck the box or whatever that hides things you cant craft if you dont have the materials required?
Also. Make sure you're going to the right crafting station. I believe this one is found in Enchanting station Lighting section.
