They changed it recently to drop only 1 cipher and apparently forgot to update the ingame info. Saw the change in recent patchnotes so it's supposed to give only 1 cipher but it would indeed be nice to show it ingame too.
Just had something similar happen to me too. I bid on an auction for 10 preservation wards about a minute before the auction was ending. The auction ended but i didn't get any mail about winning it or being outbid, so the AD i stuck in there is gone and i'm left empty handed. Really makes me doubtful of bidding on anything…
