Just got off the phone with Emirates. They said the error was due to a glitch with currency conversion to USD. They said they originally cancelled the reservations, but not the tickets. After checking with the supervisor, they can reinstate those who have their reservation cancelled (i.e. can't check the reservation on Emirates website). But if you already initiated the cancellation with your OTA with in 24hrs, your ticket is cancelled+voided, and there's no way to reinstate it, whether through your OTA or Emirates.
