The current page selection should be based on the name of the page you are on and the value of the link in the menu, if they match it should show as the same page. When I look at your contact page it seems that the links to the resources are not matching up. This might be because relative links are used. You will need to ensure that all of the css and js that are linked to on the page are accessible in the location they are referenced.
It is best to apply Menu Writer on the end page that it will be used on, the paths that are created at that time should match the location of the pages in question.
