New Confluence space - add pages under Page Tree?

[tbellmr]

Got a new space on server to do Confuence.  User asked how they can show initial pages in hierarchy below the Page Tree.  My stuff has been there for a long time so do not recall.  Her pages are created but are not shown on the left hand side.

It has been forever since I created those top level pages and can't recall how I did that.  Can someone help on getting those initial high level pages created after that sub pages can go below but frustrating that they do not appear as expected for now.
