Problem with the Header of the Dispatch theme

Hi,

I have recently changed my theme from Exhibit to Dispatch. The problem I am facing is that instead of showing 4 posts in the header only 3 are displayed. I have tried all the combinations available in WP Show Posts but somehow cannot resolve the issue, there is always a blank column no matter what I do. I even introduced a new category to check then also it showed a blank column but on the right side instead of the middle.
