Course Join Button in CoursePress Pro does not allow to enroll

So, due to limitations of the CoursePress Pro plugin (i.e. no bundles), I am using the eMember plugin for membership so members of different levels will have access to different courses essentially creating bundles.

The problem I am having is that using the shortcode [course_join_button], even if logged in, links to the course details page, rather than giving the Enroll Now option (which does show up on the course page). I cannot figure out for the life of me why, or how to fix it.

Before you ask, yes, I did try deactivating eMember first. I have tried using only the CP login rather than eMembers. But I seem to be able to enroll only from the course page, but I never want my users to be able to find the course page.
