Why do one-time donations sometimes show on donor's bank statements as recurring?
Different banks interpret the data sent by Stripe in different ways! There are some banks that look at the fields that show whether Stripe technically has a customer record that holds payment information (i.e. "is this associated with a re-billable payment method"), and if so, they show a donation as recurring. In those cases, clearing up with donors as to whether they have any current Recurring Plans or not is the best way to handle this. Stripe has more information on this bank display discrepancy in their help materials.
