Why doesn't my 'Save Deliveries' button show?

Problem

On the Project Page, the 'Save Deliveries' button may not be showing. 

Solution

This is most likely because the project part has originated from a Quote Request via the Customer Catalogue. 

It may have been quoted back to the user but they have yet to place and order or cancel it. The system will prevent saving changes to the address until the user has placed the order.
