Can not receive Sirens Tear for limit break quest

[Nealellis]

I have already picked up one sirens tear for the BLU job quest, so I know about not having items equipped. I am trying to pick one up for the limit break quest, and keep getting the message "it slips through your fingers" I have unequipped everything, have space in the inventory, changed jobs and zoned in and out. Any ideas?

Siren's tears can be traded or bazzared, so you can get one that way.

Also, do an itemsearch for siren's tears, as that message will also appear if you already possess one.
