Can't Learn Recipes from Profession Trainer

Trainers can sort abilities through a filter option in the top-right of their training window. Changing this from "Show learned" to "Show unlearned" can help show the difference between recipes you don't need to purchase and those you do.

If the trainer you are visiting doesn't provide the recipe or level you want to train, you may need to find that specific skill from another trainer. Visit major cities for the content you want to access to start your search.
