Polylang and frontpage

After installing the plugin the first thing i want to do is traslate the index page from Dutch to Eglish. But i dont get the normal menu so i need to use the WP menu ok.
If i buy the theme wil that option be there ? Also when i start the plugin polylang then i make Dutch main lang en Eglish the nr 2 wen i have done that the header is wrong all artikels are then there in the header as a link.. Main question there foris what can ido to traslate things and keep the main thing ok as in Dutch. I understand the plugin thats not the case i think but the index page is giving me issues .. Any help would be great.

The page I need help with: [log in to see the link]
