During reconciliation, the difference does not zero out even after a deposit is checked or unchecked.
This can happen when the statement date does not include the transaction date. CORE only includes transactions dated on or before the statement date during reconciliation. If a deposit is dated after the statement date, checking or unchecking it does not affect the Difference balance, which prevents the difference from zeroing out.
To resolve this, edit the reconciliation and update the statement date so it is on or after the deposit’s transaction date. When the statement date includes that transaction, CORE recalculates the reconciliation and checking or unchecking the deposit correctly updates the difference balance, allowing it to zero out.
