How can I add an image with text to this page

24 0 6

Hi all, so I have this page on my site. I added as many sections as I could to make it better but am struggling to add a hero to the page. When I add more than 2 of the same sections it crosses over and edits both of them instead of one. I'm mainly looking to add an image with text but I cannot find out how to do that in my code. I am using the theme grid. Here is the page I'm referring to.
