3D FlipBook - 3d flipbox pages - Archive

Page Title: 3D FlipBook Archive https://plumbingworldhelps.co.nz/catalogues/

How do I edit the likes of these self-generated pages? I went to edit with divi, and the body is unclickable. I tried to create a new page with the slug /catalogues and when you view the page it shows the default archive content.
