Did you reverse the checks in BankRec or Payables? They must be reversed in BankRec first this will then post the reversal in Payables (or set the status to pending in older versions of Payables)

Voiding checks is a feature that should never have existed, so I don't see this coming to BankRec.

Based upon your description of the problem, you should now reverse the checks in BankRec and be good to complete your reconciliation. If you can't then something else is wrong.

Did you restore BankRec after reversing the checks (putting BankRec out of sync with Payables)?

Unfortunately this is not a problem that can be easily dealt with in a forum. You should contact your Adagio dealer for assistance.
