Why is a single Cross Reference text turning red after doing an Update?
After updating a large book in FrameMaker10, the same cross-reference made in a couple of chapters is turning to red text. It is set as Heading 2. I tried to deleted the heading and re-typing it. I tried to change the style to Body and back to Heading 2 but all references to it are turning to red text after I update the book. Any idea what is wrong and how do I fix it? I am using unstructured version. See image.
