@Mirko034: Yes please wait for new version update. Where the theme will work fine in Version 0.2. From Version 0.2, all page menu and custom menu will work. It will show the select page in the menu and if not found the page then it will show Menu as title. We have already push the theme to update in WordPress.org. So, it depends on the review team to make it live.
After the update, please clear your cache and it will work fine. So, now please wait for use Custom Menu. While using Custom menu add your homepage from “Appearance => Menus” you will see the Pages Box, from there click on “View All” and select Home:Home and click on Add to Menu.
