After Update – Mobile Menu Issue (menu won't close)

Recently updated to WP 4.3, and Customizr Version: 3.4.6.
Update appeared to go well, except for viewing my menu while on a mobile device. I can open the hamburger menu but can’t close it without clicking on a link within the menu.

I’ve made some Custom CSS changes which still appear to be there.

The key for these changes was to make the social icons, logo and menu on the same line. I don’t know what else i’ve put in there without comments.. sorry for the newb in me!

Anyway, just trying to figure out the mobile menu once more. Thanks!

Custom CSS:

.tc-header .social-block { width: 30%; }
.nav-collapse.collapse { clear: none;}
.tc-header .navbar-wrapper { width: 90%; margin-left:10%; margin-top: -65px;  }

.page .entry-header { display: none; }

/* START OF Change Page background color */
body {
    background: none repeat scroll 0 0 #FFFFFF;
}
/* END OF Change Page background color */

/* START OF Change Grey Bar between Navbar and Slider */
header.tc-header {
border-bottom: 0;
}
/* END OF Change Grey Bar between Navbar and Slider */

/* Remove grey bar from footer  */
footer#footer {
border-top:     none;
}

/* START OF Change the size of the Social Icons */
/* Header Social Icons */
.navbar-inner .social-block {
font-size: 0.8em;
}
/* Footer Social Icons */
.colophon .social-block {
font-size: 0.8em;
}
/* Sidebar Social Icons */
.tc-sidebar .social-block {
font-size: 0.8em;
}
/* END OF Change the size of the Social Icons */

.woocommerce ul.products li {
    width: auto !important;
}
