Setting and adjustments for static main page

Hello everyone. Excuse my English!

I am using the theme: RIVERBANK and have made various adjustments.

Somewhere I put static main page but I don’t remember where that was. However, this static page is not displayed either. In Pages there is a ‘Home Page’ that is not called.

What do I have to adjust in the template: ‘Home’ so that the ‘Home’ is displayed on the website?

Thanks Klaus
