If you have saved a card in the Billing panel, your receipts might say "Recurring Payment" for purchases that are not a part of a recurring subscription plan.
Seeing "Recurring Payment" does not necessarily mean you are subscribed to a recurring billing plan (unless you're a Poached Member). While this may be confusing, it is necessary to save your payment information for future use, without making you re-enter the CVC code of the credit card for each purchase.
