With version 2.2 (and before) of Confluence, when I changed the size of the "Recently Updated" section on the dashboard and returned to the dashboard, it would remember what size I had set the list to. After moving to 2.2.9, I can change the size of the list OK, but when I return to the dashboard it goes back to the smallest list size (10, I believe). It's like it is no longer saving the preference of what size I want the Recently Updated list to be.

The version 2.2.9 is a brand new installation, we didn't do an upgrade from 2.2 to 2.2.9. We're exporting some spaces out of the 2.2 version and importing them in the 2.2.9 version.
