During the check-in process screen there is an option to just click a "check-in" button rather than the "Check-in/Guest Ledger" button. Please remove the single "check-in" button because if a guest has paid their deposit in advance and this button is chose rather than the "check-in/guest ledger" button the system will charge the guest credit card again during the check-out process. This results in having to apply refunds and dealing with very upset guests.
