What you are seeing when you click on "Tatoo tips" (the three columns with the white articles boxes), is actually the Articles category page. It's not a Wall, it's a category page. It has absolutely nothing to do with the Wall.
Why do you expect to see a Wall there, when it's a category page?
It's the same thing in our demo. When you click on "Action", you are redirected to the Joomla articles category page.
