Pages hidden in page tree in new space

[Simon K.]

I can not see the sub pages tree anymore in my new space as long as the "Overview"-page is displayed or the "Pages"-root:

But as soon I change the page to a sub page (some pages are displayed as tiles in the main section when I click on "Pages") the whole page tree is then visible.

What can cause this issue?

EDIT: I'm also confused about why those direct sub pages are classified as hidden:

But on the other hand those "hidden" pages can be reordered. Those are the same pages which are visible if we open them directly.

EDIT2: I played a bit by setting different pages as home page. I looks like the page tree is showing only the sub pages of the selected home page. Is that an error or expected behaviour? I just want to see the page tree of the whole space - not for only one specific page.

Hi @Simon K_ , is the Overview page your Home page? (see Space settings > Space details > Home page)

I migrated an existing single page (with all sub pages) from another space to this new space. Afterwards I moved sub pages to the space's root. Everything worked fine until then.

Since I don't want to loose the whole change history of the previous start page I defined this old page as new home page. Maybe the tree got lost in that moment.

So no, the current home page is not the original generated home page.
