This is a bug and not easy to replicate. Upfront creates a region with blue background.
1 - Create a page
2 - Add a region bellow the main one with will become a new main region.
3 - Remove all the regions bellow
3 - Add new region above the first created region
Or follow these steps:
1 - create a new page
2 - add a region bellow the main one with will become my new main region.
3 - remove footer area and re add the Global footer region that I changed
4 - add the Get Started region above that which I created
5 - remove the page template main section ( menu left -content right )
6 - add new region above the first content region I created which was to become the tile region....
