When you use Cite While You Write to add citations to your Word Document, hidden field codes are added, and cause the citations and the reference list to be shaded grey.
It is critically important that you use correct procedures for adding text and deleting. Any changes you make without using Edit and Manage will not be permanent and will not remove the field codes correctly, risking corruption of your Word document.
