Menu not showing on index page - smartphone view

The menu does not appear on the index (home) page of my site 2-XL.net, when viewing on a smartphone, e.g. iPhone and Galaxy Note 1. The menu does appear on any other page. Included are screen shots of the home page and blog page. Note that the menu does work on the home page, only users wouldn't know it is there. Thanks.

Appearance > Theme Option > Styling Option > Custom CSS

Code:

.mobile_nav {
margin-bottom: 30px;
