The post carousels and grids don’t have this as an option, you can add it though.
You can edit your \wp-content\themes\fortuna\includes\shortcodes\vc\boc_post_grid.php file and after this line:

$str .='<h4><a href="'. get_permalink().'">'.esc_html(get_the_title()).'</a></h4>';

You can place something like:

if(!empty(get_the_category())) {
    $str .= '<p class="mt10">';
    foreach (get_the_category() as $catItem => $cat) {
        $str .='<span>'.$cat->name.'</span>';
        if(($catItem + 1) != count(get_the_category())) {
            $str .= ' | ';
        }
    }
    $str .= '</p>';
}

Obviously you can style this anyway you like. Good luck!
