I have a Master with section and page number fields. Each document page has a background photo set to "Move to Back" with other objects in front of that. The section and page numbers are visible on those pages. When I move (drag and drop from the "Pages" list) a page from one place to another position in the document, both the original location and final location pages hide the Master Fields - they do not appear. The background photos are still set to "Move to Back" but the fields are hidden "behind". Remove the background photo and the fields are still on the page. Have to remove and replace the background photo and "Move to Back" to fix it. This has a randomness as some other actions can cause the hiding of the Master fields (just opening the working document, for example).
