Steps to reproduce:
- Login as a user or admin
- From the wiki homepage hover over the "Sandbox" space and click on the small book to its right to see the "Space Index"
- Sort the elements in the table by "Date" ascending
- Sort the elements in the table by "Date" descending
You can see from the screenshot that the "WebPreferences" page isn't included in the ascending sort. Another thing I noticed is that the same page (WebPreferences) disappears completely from the "Page" tab when sorting by "Date" descending and also the "WebHome" page appears twice.
This bug also reproduces on the "Document Index" page.
