OK Tom, got it figured out.
I had renamed my Front (Home) page home.php and then created a separate content-frontpage.php to display the front page content. In that content-frontpage.php file I removed all the headings and meta data and sidebar.
My blog (News) page was obviously using home.php as it’s template. I then renamed home.php to front-page.php and that resolved the matter.
Thanks for pointing me in the right direction though.
