With 30301, the ‘Patron account expiry’ message line doesn't show in 'Default messaging preferences for this patron category' if 'Enforce patron account expiry notice' is set to Yes. This means that if the notice is being enforced and the library needs to edit its default preferences, they have to switch 'Enforce patron account expiry notice' to No, click Save, and then open the category back up for editing. However, switching 'Enforce patron account expiry notice' from Yes to No un-sets the existing preferences rather than just showing existing selections for editing.
