Learn2 Page Nav Not Working Correctly

As I create/add new pages, the left (previous page) and right (next page) arrows on each chapter and docs page of the Learn2 theme are not going back or forward to the next page in the menu, and some don't go anywhere, the arrows just refresh the current page.

I've cleared the cache and double check each page's settings (nothing unusual there, I've left the default options set).

Suggestions?

I found the answer ... for the Previous and Next arrows to work on each page the current page AND the Proceeding/Following pages MUST be associated with the "docs" category.

This is the correct answer :)
