How to use an existing static front page with Upfront theme?

Hi,
I really like the Spirit theme and want to use it for my site, but when I have it activated it looks like the "front page" is not any actual existing page. Eg when I look at the list of site pages, the static front page is generally tagged with "front page" but that tag is not showing at all with Spirit active. Can you advise any further on this?

Thanks,
Richard
