Cannot Discard Duplicate Artifact Armor Set

[Serra_Frist]

Ok, so I redid the Black Mage quest line and I realized that I received another full set of the BLM AF. I had stored my original set in the inn room while I was doing the quests and now I can't dump the new set to get back my inventory spaces. I have 2 sets of the same unique armor and I cannot get rid of them. Please help me get rid of this. It's unfairly eating up inventory space for something that was an obvious oversight. I tried putting the AF on a retainer and releasing it, but it didn't work. Please don't ignore this post. I don't want another "moogle pie stuck in bazaar" issue like in FFXI.
