I fixed by going into theme file editor, partials, custom-home, featured-area.php.

I added a new boolean var to allow me to turn on and off the feature.

<?php
$turn_on_feature = true;
if ( $turn_on_feature && isset( $responsive_options['feature'] ) && '1' == $responsive_options['feature'] ) { ?>
<div id="feature_div" class="custom-home-feature-section grid">

In my case, I was not using the plugin “Responsive Ready Site Importer”. I tried disabling all plugins, no change. I also looked through logs, and found no errors. There are a few 404s but they do not look related:

Here is the customize screen and the same with the dev tools window showing network load and console.
