“Choose what to display on the main shop page.” Select Show categories as seen in the Screenshot below.

For users who has a different/custom page for their shop you can edit the wc-hide-categories.php file 
Find line # 127 and remove //
<pre><code>//$mwd_opt4 = in_array( 'product_cat', $taxonomies ) && ! is_admin() && is_page('YOUR_PAGE_SLUG'),
</code></pre>
Then find line #129 <code>/*|| $mwd_opt4*/</code>
Change to 
 || $mwd_opt4

<pre><code>// Uncomment the function below if you also want those products hidden
/*
 add_action( 'woocommerce_product_query', 'mwd_hwcosp_remove_product_in_cat' );

 function mwd_hwcosp_remove_product_in_cat( $q ) {
 //hwcosp_global is the databse row entry
 $opt_terms = get_option('hwcosp_global');

 // Processes our users data to the way we want it from above
 $data = mwd_hwcosp_comma_separated_to_array($opt_terms);

 $tax_query = (array) $q->get('tax_query');
 $tax_query[] = array(
 'taxonomy' => 'product_cat',
 'field' => 'slug',
 'terms' => $data, // Set Category Slug which products not show on the shop and Archieve page.
