Change the page template used by course press pro?

I’m using Divi as page builder because upfront was discontinued. I’ve created my site with the blank page template instead of the default template because I don’t like the visual look of it. But when i made some coursepress pages they use the default template instead of the blank one.

This is a coursepress page, which has a menu on the right and left:

The single unit, should have a similar look, but it looks like this:
