TOPIC: Discount code use count for members in a group registration

We seem to have a problem that we're not getting the correct number for the use count of a discount code when the code is used for members of a group. It counts individual registrations correctly but ignores uses of the discount code when it is part of a group registration. We have the discount code set to be entered for all members of a group.
Is there something else that is needed to make this count correctly?
Thanks,
