Styling report

I just started using kobotoolbox today, have to read many tutorials, but when it comes to styling the report to vertical, pie, or donut, nothing happens, may I know why is that? or have I skipped/ignored something?

Yes, the second step seems to be different from what I see, the Edit Report Style

I already created a Custom Report but, no dice
