Trouble with configuring

The theme looks absolutely promising and I love the many configuration options. However, I am trying to figure out how they all work.

First off: I could not get the slider working through Homepage Sections, until I figured out I had to ALSO activate it in Innerpage Settings. A bit confusing, but ok…

But I still can’t get all the other Homepage Sections working. I activated Promotion Block Section, Widget Area 1 Section and Product Section, but nothing changes on the homepage…
