Menu not working and weird

Hi there, I just bought the theme 2 days ago, I just installed it with the plugins required and try to import the xml to get the default layout. But the menu got weird and some icons are not where they should be (Search, Connect).

As for the menu, there’s no animation + the HTML that normaly goes into the menu is displayed in front of the page … you can see it if you check the date for example.

Note : I use WordPress in french
