Home Page

Hi, I imported the template website to see how some features were created.
There were 9 different versions of the homepage and I would like to choose version 2.
I’ve gone to what I think is the correct place to change it
Appearance -> Themes -> Static Front Page
And set a static front page set to the v2 home page.
No matter what I try I cant get the home page to change from the one which was set originally.
Please could somebody help?
Many Thanks
