When a guest uses their banked rewards, they are not being gifted the Base Redeemable - banked rewards pass through the Base Redeemable and utilize its logic but there is no actual gifting taking place. On the app, users will see the name of the Base Redeemable along with any text when redeeming along with the redemption code so to avoid any confusion, you may wish to change the name of the Base Redeemable to a generic title such as "Banked Rewards" and remove any text from the description.
