Issues with courses in CoursePress Pro

Hello, I'm not certain whether this issue is directly related to my install of CoursePress Pro or Marketpress, however I was checking my site last night and it appears that the "Add to Cart" or "Buy Now" buttons are no longer displaying on the Course page.

I made an attempt to set up another course and see if the problem would replicate and the same issues appears.

I must admit that I have made some changes under "Products" with the display options and its highly possible I have done something silly.

I have also followed some tips from the support forums, including turning off any caching plugins, but no improvement unfortunately.

I would really appreciate some expert help as I was hoping to launch the site today, so this little snag has put me back a little.
