Menu bar navigation problem

Hello there,

I am having problems with my website menu bar navigation. When I click exactly on the page name, it is directing to my home page but not the page I clicked. If I click above or below the page name on the menu bar, then the page is opening. I want the page to open when I click on the page name. Can someone please tell me how can correct this?

Here is my website in case you want to have a look at it

Thanks.
