Problem with the menu ext parameter plugin

i tried to make 4 columns with gk menu extended parameter plugin but only two columns displayed.when i zoom out the webpage i can see only three columns horizontally and one vertically.Please provide me the solution.

Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
