parent pages issue

[rainydaypixels]

I have used parent pages since I started using InDesign 4 years ago. I made the latest software update today and am suddenly having this issue:

A-parent is applied to 4 pages (two spreads). A-parent consists of a running header on the top (left and right, centered), and page numbers on the bottom (left and right).

On the first spread, both headers and page numbers appear on the designed page. On the second spread, both page numbers appear, but only the right header appears.

The thumbnail overview clearly shows that the A-parent is applied to all four pages.

I tried substituting a copy of the A-parent to the page that is not showing the header. No difference. I also tried susbstituting the [None] parent. This works, but of course it's not the parent I need there.

I also tried creating an alternate A-parent, moving the header text to the bottom of the page, next to the page number. In this case, both text and page number show up on the designed page. It's as if something is blocking the upper portion of the parent from being displayed on that page only.

I'm sure this is something stupid that I'm not seeing . Any idea how to troubleshoot or fix it? Thanks in advance.

Are your headers based on variables or directly typed in?

Any chance your Cntl/Cmd-Shift-clicked on the header?

If it's an old file, created in some older version of InDesign and then multiple InDesign updates were installed - and you were only doing Save - then maybe your file is corrupted?

Try IDMLing - export as IDML, open, save with a new name - do not overwrite your original file.

1. Are you sure you did not accidentally override and remove the running header?
2. Are you sure that the header was not covered by content? To avoid this, work with layers and put page numbers and headers on a layer above all other layers. 
3. Could text wrap affect the content? Apply the used object style with the property to ignore text wrap. 
4. To get cleaner files, rename the generic names of masters/parents with more descriptive name and letters or numbers. Don't end up with several identical named masters/parents as it cause confusion.

I've had a situation in the past where if a running header text frame 'touched' the page edge at the spine - the header on the other page disappears in the layout. 

I never have text frames touching on Parent Pages since - well could be this but I don't really know, just remembering a scenario I faced before maybe it helps.
