Hi Steve,
Let me provide you the information you need.
Fields, content controls, cover page: These display in the document as expected in Reading view. In Editing view the content of fields and content controls are displayed but cannot be edited or updated. A cover page appears as a series of placeholders for elements like text boxes.
Refer the following link to fix the compatibility issue.
Hope this helps. Let us know if you need further assistance.
Thank you.
