When the status of a tenant changes to 'Closed', any bank statement import rules associated with that tenant are now automatically deleted. If the tenant is later re-opened, new rules can be created.
This help to clear out old rules which are no longer required to make the rules list less cluttered. It also helps in situations where a tenant has set up an automatic payment, and forgets to cancel it with their bank when they leave. When you go to import your bank statement, these transactions will stand out.
