I have a new A/P clerk and recently after a batch of cheques was done, she accidently clicked on that cheques were not printed correctly and then ran the cheques again and printed the cheques again with new numbers on paper. So now all of the cheques that were printed correctly, originally, are clearing the bank account, and duplicate cheque numbers are starting to happen with the cheques that were printed on paper instead of our cheque stock. Normally I know I could use a back-up and do that, but I didn't find out about the error till today and it was done back on May 14th. The cheques haven't been posted to ledger yet. Just wondering what I can do.

Thanks,
