Thanks @bdown111, that helps.
You can replace this section of your child theme’s page.php:
<!-- Page Content -->
<div id="page-<?php the_ID(); ?>" <?php post_class('entry entry-page'); ?>>
<?php if($kale_pages_featured_image_show == 'Default' && has_post_thumbnail() && $kale_pages_show_thumbnail) { ?>
<div class="entry-thumb"><?php the_post_thumbnail( 'full', array( 'alt' => get_the_title(), 'class'=>'img-responsive' ) ); ?></div>
<?php } ?>
<?php if($kale_pages_featured_image_show != 'Banner' || !$kale_pages_show_thumbnail) { ?>
<?php $title = get_the_title(); ?>
<?php if($title == '') { ?>
<h1 class="entry-title"><?php esc_html_e('Page ID: ', 'kale'); the_ID(); ?></h1>
<?php } else { ?>
<h1 class="entry-title"><?php the_title(); ?></h1>
<?php } ?>
<?php } ?>
<div class="page-content"><?php the_content(); ?></div>
</div>
<!-- /Page Content -->
With this code:
<!-- Page Content -->
<div id="page-<?php the_ID(); ?>" <?php post_class('entry entry-page'); ?>>
<?php if($kale_pages_featured_image_show != 'Banner' || !$kale_pages_show_thumbnail) { ?>
<?php $title = get_the_title(); ?>
<?php if($title == '') { ?>
<h1 class="entry-title"><?php esc_html_e('Page ID: ', 'kale'); the_ID(); ?></h1>
<?php } else { ?>
<h1 class="entry-title"><?php the_title(); ?></h1>
<?php } ?>
<?php } ?>
<?php if($kale_pages_featured_image_show == 'Default' && has_post_thumbnail() && $kale_pages_show_thumbnail) { ?>
<div class="entry-thumb"><?php the_post_thumbnail( 'full', array( 'alt' => get_the_title(), 'class'=>'img-responsive' ) ); ?></div>
<?php } ?>
<div class="page-content"><?php the_content(); ?></div>
</div>
<!-- /Page Content -->
