I'm using Confluence 3.5.13 for an application documentation project and I find that when I go to output a selection of pages using the Advanced-Export > PDF Export functionality, some of my pages are out of order compared to the hierarchical page tree that is displayed.
The pages that are out of order were moved from a section of the space higher up the list of pages to one lower down the tree a week or so back.
Is there a way to address this issue?
