Two problems with theme

Hi, My website www.vanwulfen.com is now live. There are two problems I hope can be fixed quickly: 1. When displaying the site on a phone (both iPhone and Android) my site's submenu's are not displayed in the menu; 2. When shrinking the window size on a computer, eventually the classic menu will revert to the modern one, as intended. However, when doing so the social menu will duck under the normal menu, before the switch is made to the modern menu. Thank you for an otherwise great theme! Victor
