Item Disappeared after removing it from the market board

Date: February 24th 11:30pm CT Time
Location: Mists, 1st Ward, East Mist Market Board (X:13,Y:11)
Action Used: Return Item to Inventory (From Market Board)
Item: Platinum Bangles of Healing

I had the Platinum Bangles of Healing on the market board, as I was trying to sell them. I decided I wanted to use a different Retainer to sell the the Platinum Bangles of Healing. I right clicked the item from my retainers "sell items on the market board" tab and selected, "Return Item to Inventory". In my Chat log it said, "Item returned to Armory Chest" I dismissed my retainer, summoned the one that I wanted to sell the Platinum Bangles of Healing on. Opened the "sell items on the Market Board", opened my Armory Chest, and the Platinum Bangles of Healing were not in my Armory Chest. I personally checked all my inventories, including my retainers, and I also did a search for the item, which came back with the results "Item not found".

The Platinum Bangles of Healing completely disappeared after removing them from the Market Board.
