GD2 page setting

Hello,
I am using the theme surpreme directory and have just converted from GDV1 to GDV2.
With GDV1 there had been the page “GD Home” with the nice wide homepage design of surpreme directory. I had renamed this page into “Suche” which makes more sende in German.

Now (since GDV2) my former homepage “GD Home/Suche” has the design of a “normal” page with a frame, not the nice wide design of the surpreme front page / home page.
Instead there is another page “GD Location” having this nice wide homepage-design.

When I look at the page settings, I cannot figure out where to determine my Homepage. And there is this GD Location page …is this Location page automatically the new home page?

When I choose my old home page “Suche” as GD Location page, the design of this page is still NOT the nice wide design of the home page.

So do I determine my home page with GD Location?
Do I have to choose Location page as GD Location?

Or how can I determin my previous home page as home page, including the nice wide homepage design?

Please help.
Many thanks
Birgit
