MasterStudy and Neaver Builder

I’m looking for a plugin for a client and keep running in to the same issue – not compatible with Beaver Builder. The client wants to use Beaver Builder to create lesson pages. I was able to use it on the course page when I installed on my test site but not on lesson pages. When I try to launch BB, it redirects me to page not found. Is this something that can be fixed? Also, when I try and view this lesson page, it takes me to the WP sample blog post page – this is the lesson page https://thctest.space/stm-lessons/stm-lesson-1/ but it goes to this page when you try and view it https://thctest.space/hello-world/

The page I need help with: [log in to see the link]
