Sorry, but no sympathy here (and I do not work for FR). Common sense says you input into the system when booking the exact details on your passport / ID / credit card. Then, no possibility for confusion.
Simples.
Maybe you should try booking for a group of people, some of whom have a variety of ID in more than one name. You would quickly find that the whole business becomes extraordinarily time consuming when all you really want is 12 seats.
