Duplicate checks in account reconciliation

For the past few months, the account reconciliation is showing a duplicate check but with a zero balance. When you click on the zero check, the check appears with the correct amount. After 3 hours on the phone with Sage support, the answer was to delete the check and re-enter it. There has to be a solution to this. In the past, this would be rectified by running a data verification. September's reconciliation has not been corrected by data verification. The operating account does not have this issue, it is only the payroll account.
