Hi,
The cluster pages are making Lesson crazy Use Branch Table page type instead of Cluster page type. For example, make "Poor Time Management" a Branch Table. I think that will solve your problem.
Cluster pages are special pages, really an advanced Moodle feature. Do not use them to hold content and only use them to select random pages.
FYI: What happened in your example? Students will not see the content of the first cluster page but will be immediately sent to the page in the cluster page's jump. If you changed the jump in the Branch Table to "Goal setting", then students will jump to "Getting the Big Picture". Think of Cluster and End Cluster pages as pages that are hidden from students. (You discovered an exception to this rule).
When you first start making a Lesson, only use Branch Tables and Question page types. If you want to use clusters, put them in AFTER page types that students can see.
Hope this helps Chris
