AX 2012 Bank Reconcilation - Unable to reconcile

My client has completed a bank reconciliation. Somehow they were able to reconcile the account but when they subsequently review their bank rec it shows that even though it has been reconciled the amount to reconcile value is populated. which should not be the case. Trying to complete a subsequent bank reconciliation they are unable to reconcile as even though have marked all the appropriate transactions it is now displaying an amount to reconcile which should not be appearing. Would appreciate any insight that can be given

The below post explains you why the issue happened and read the comments to find how to resolve it.
