Surcharging on Registration Form with TE

We have a customer (BAM 53760800) who has TE and is surcharging and set up a registration fee. Surcharging does not apply to registration form fees for customers who are setup on TE, but seeing a fee on the form below their registration fee of 0% + $0 with no explanation when they know they are surcharging a set amount on credit cards was a bit alarming for them, especially since they cannot control the surcharging settings themselves.
