I have Coursepress Pro Plugin and Theme installed and noticed that the course units appear to be using the blog template. This isn't good as the page titles will always say 'Blog Posts'. Please see pages titles of these pages:
Blog Page: https://mumsbusiness.club/blog/
Course Page: https://mumsbusiness.club/courses/wordpress-essentials/units/test/page/1/
I'm sure its something I have set up wrong as they shouldn't be using that same page template, but can you please take a look?
