Issues with Child Theme and Visual Composer

I have a clean install of WordPress with the Safeguard theme installed, the required plugins, and the demo content. If I switch to the supplied safeguard-child theme I lose some functionality and styles.

So far I’ve noticed that the Visual Composer Front-end editor goes missing from the page editor and the Visual Composer Role Manager options.

I also lose all of the custom Visual Composer CSS classes/styles, example, the below is only present when the parent theme is active.

.vc_custom_1453985067676 {
padding-bottom: 70px !important;
}

I attached two example screens showing the homepage as seen on the parent and child theme. You will see the difference in spacing.
