Home Page Change Not Showing

I am using the Primer Theme – just installed it a few weeks back. I attemtped to change the front page to a new home page. I found the settings in Settings and I thought I had it. However, when go to the URL, the site that is diplayed is the native theme with a few exceptions. The menu changes I made are reflected and the Tagline change is there. The site title does not match what I entered into the Theme Customization. When I am in Theme Customization, the page looks fine – as I expected.
Then I view the front page under Pages, I get the Theme Header, not the header that I wanted.

As a temporary fix, is there a way to change the Theme text, “Make a bold statement”, the text that follows and the ‘get started’ button?

Thanks
