Adding pages to starter website

As a beginner I am trying to add some pages to my imported starter website using Blocksy theme with Gutenberg / Stackable – when I add a page ( Dashboard / pages ) and update the page title and heading they can be seen in published website behind my logo – see example page

Also did manage to add test page which looks good but when in Dashboard / pages I can’t view the content but pleased it has the other pages and take action button listed

Any assistance appreciated ( have viewed some beginner videos )

The page I need help with: [log in to see the link]
