Page Properties Report macro not finding some pages

I have several pages with a Page Properties macro on them, all children of a page with a Page Properties Report macro. I'm restructuring my space and moving the children out to a different parent in the same space. When I do that the pages disappear from the Page Properties Report.

They're still in the same space, I haven't changed the labels on the pages I'm moving, and I haven't got any other filters active afaik.

How can I make the Page Properties Report show all the pages in the space that match the label?
