Featured Content Columns and Number of Featured Contents

I am having a problem with the featured content section in the Customize section. I have set the layout for 3 columns and 6 featured pages. However, I am only given 4 "Display Content" slots for Featured Content 1, Featured Content 2, Featured Content3, and Featured Content 4. There is no slot for Featured Content5 & Featured Content 6. What am I doing wrong? I have refreshed the page, saved, refreshed again, and even waited overnight to try it on a different computer in the morning. Nothing works. Thanks
