[Koha] Email notices - changing the From address

When the system sends out notices they are being sent from koha@explorethelibrary.com and so in most email clients they list the sender as "koha". Our patrons aren't going to recognize that so I've been trying to set it to add "Ash Flat Library". The usual method would be with quotes and brackets: "Ash Flat Library" <koha@explorethelibrary.com> This puts double quotes around the From and then shows nothing at all for the KohaAdminEmailAddress variable next time you open the Admin. Trying to escape the quotes with a slash doesn't work. No quotes fails by giving just Ash and nothing else. Single quotes fail as well. What am I missing?
