Duplicated Event Item will not discard from inventory.

I placed a green Pumpkin Head from the event All Saints.. in my room armoire.

I then picked up a second Green Pumpkin head later in the week while the event was still going on.

This item does not have the option to Discard. I can only wear it or repair it.

I am sure this is due to a glitch of being able to pick up 2 of the same UNIQUE items.

But.. I want to discard 1 of them. Any help would be appreciated.
