Comment author name incorrect

If a commenter is a user/admin, not a guest author, it replaces the commenter’s name with one of the admin’s. We have changed that admin’s name to Romance University but it was showing that admin’s name before that. If we disable the plugin the correct name is shown. I submitted a ticket but haven’t heard back so thought I’d try here as well.
