Featured content; only 3 pages instead of 4

Hi, i would like to show 4 pages on my featured content slider. so i made this selection within the featured content options: Select Featured Content Layout: 4 columns No of Featured Content: 4 however i only see 3 Featured Pages. How to change it to 4? is it because i use the free version of the theme or is it something i do wrong? Thanks for your help! Regards, Marike
