Features not working in Enfold 1.91 with WordPress 3.6

Hey,

Recently brought and put together a website for a client with Enfold but a lot of features don’t seem to be working or I’m ignorant of why there not working.

Here is the Website: http://heartnsoulmatters.com

Here are the problems im having that I desperately need help with:

Responsive Design:

1. Menu Disappears at mobile size, no drop down menu

2. Big Space under Layer Slider at mobile size

General Theme problems:

1. Back to Top Button Doesn’t Appear

2. Menu doesn’t get smaller/Shink on scroll

3. Image’s from Media box animations dont work (Using Latest FF and Chrome Browers, and IE9)

Everything on the site is out of the box , The only things that I have have changed is 2 quick CSS

.title_container {

display: none;

}

#top #menu-item-search {

display: none;

}

So it should work, please advise me why these features arn’t working.
