Reattaining AF with no ability to discard

Today I redid my WHM and WAR story lines. I already had completed them in 1.0 and had the AF in storage. Without thinking, I failed to pull my AF out of storage. Now I have a 2nd set for both jobs that I cannot store, nor can I discard. Inventory -10 with no way to fix it. If you are unable to discard the 2nd set, there needs to be a way to prevent the character from receiving it in the first place.

Additionally there needs to be a way to discard something when this occurs.

Character: Azaka Tonnerre
World: Balmung
