Suppose you made a huge mess of the ticket selling arrangements for a major hypothetical music festival, and subsequently discovered that your woefully inadequate hypothetical ticketing system had issued hundreds (or thousands?) of duplicate ticket orders to unsuspecting ticket buyers. Suppose you then discovered that despite the entirely fictional event having officially “sold out”, you were left with a huge number of cancelled (and therefore unsold) duplicates.
(a) publicly announce that there were still tickets available for the event, causing an unholy scramble for tickets, and overloading your system. Again.
(b) quietly sell off the remaining tickets on your website without really telling anyone?

Official line: There will be no further issue of tickets. Duplicate orders have been cancelled and returned to the system and have all now been sold. Any further returned tickets and duplicate orders will be absorbed by outstanding needs.
