using WP Ultimate Grid plugin for the posts on front page

I am using WP Ultimate Grid plugin to show 4 posts in the grid format. The first time i create the grid, it shows only 4 posts which are in the grid format. When i refresh or come back to the screen from a different post, i see all the posts below the grid. I want only the grid and no posts showing on the front page.

I enabled the support access. URL: http://www.chelmsfordsaicenter.org
