I had an item listed which had attracted a bid and was due to end earlier this evening... when I searched for the item it appears as an unsold item. What I forgot was that there was a reserve on the item and that reserve wasn't reached, hence it became an unsold item... but the status message reads wrongly as it states:

Status : You were the seller of this auction but no bids were made. Feel free to review the details and outcome of the auction below. The link to repost this auction can be found just below.

It should state that the reserve wasn't met despite a bid being made... then I would have realised why it was in my unsold list!
