Hi simonneale,
Thanks for bringing this up. I totally get how this could be bugging you. This happens because the bank reconciliations in MYOB follow a certain order, where the closing balance is figured out based on the last reconciled balance plus the transactions you've ticked off. Usually, editing reconciled transactions can indeed lead to them becoming unreconciled. Given the extensive period affected, you might want to try doing a reconciliation set for a future date to see if that balances things out. If that doesn't work, you'll have to undo the reconciliations back to where the imbalance first popped up and then redo them.
Feel free to reach out anytime you need further assistance.
Cheers,
Princess
