Unable to ad Post author shortcode/link to my posts

I cannot seem to make the post author link visible for any of my posts. When I first set up the theme (Mia by 17th Avenue), I removed the shortcode from the ‘Single Content Entry Meta (above content) box’ within Customize>Theme Settings > Singular Content. I have tried to add a shortcut back in to display the author of the post but nothing is happening. I have also tried to add a date shortcode but still, nothing is displaying.

I removed the category shortcode from this box, but this is still displaying above the article.

Any help would be very much appreciated.
