I prefer my order to be first name and then last name. It is displayed this way, but it sorts by last name, first name. I've found the tweak spot to change it, but after I do so the apply button is greyed out. I'm sure I'm doing something wrong, but I'm not sure what.

This is what it is:
author_sort_copy_method = 'comma'

This is what I'm trying to change it to be:
author_sort_copy_method = 'copy'

Could someone please tell me what I'm doing wrong, this is very aggravating.
