Hi Eurofence
Thank you for the update.
Did you run the Bank Reconciliation report and find some accounts not appearing on the report? If so, first of all on the report screen, please click on the 'Accounts' button to check if all the desired accounts are ticked. After that please go to Banking > Reconcile accounts, select the account in question, does it show any last reconciled date under the account field?
If the correct last reconcile date is showing on the Reconcile Accounts window but not on the Bank Reconciliation report, please do provide a screenshot showing the reconcile account window, the report and the accounts selection window of report, so we can look into it further.
