Featured Content Layout Four does not work correctly.

I want to make the Featured Content with 4 columns layout. The layout shows 4 columns but The No.of.Featured Content always three. It shows only Featured Page 1, 2, 3. Pls help me to add one more page to Layout Four. https://lh3.googleusercontent.com/-aZNHbuC_ZeA/VglmqtxPnaI/AAAAAAAABzo/n6fWtJ421PA/s912-Ic42/Screen%252520Shot%2525202015-09-28%252520at%25252023.09.21.png
