Featured post slider not showing properly

Hi Does anybody know why my featured post slides aren't showing properly? I have added 2 different posts and set the post number in theme options under the featured post slider tab. The first picture is appearing fine, however the second one does not show at all. Does anybody know why this hasn't worked properly please? Also, is it possible to resize the width of the main content box in this theme? If so could somebody please tell me how i can do this? My site it global-gurus.com Many thanks in advance :)
