Hello,
The Blog section doesn’t have any settings. That’s why there doesn’t show any options for Blog. On the other hand, you can’t use a section twice a page. That’s why another Flat Content setting is not showing. For this reason, we made two Flat Content sections to use on a page.
Moreover, you can easily make a section with an image on the left and content on the right or an image on the right and content on the left using the Flat Content section. You can use the Flat Content section’s editor like the WordPress page/post editor.
Please Note: This theme was developed in 2016. Hence there have some limitations to content editing.
Best Regards,
