Google Strutured Data Tool errors

Hi, I love your theme, but my webmaster tools is telling me there’s error in the rich snippet … stuff..

Anyways,

To solve this error, I have to edit single.php manually and adding
entry-title
to line 13:
<h1 class="post-title"><?php the_title(); ?></h1>
to make it read:
<h1 class="post-title entry-title"><?php the_title(); ?></h1>

To solve Error: Missing required field “updated”
I have to add <span class=”date updated”></span> to line 14:
<p class="post-byline"><?php _e('by','hueman'); ?> <?php the_author_posts_link(); ?> &middot; <?php the_time(get_option('date_format')); ?></p>
to make it read:
<p class="post-byline"><?php _e('by','hueman'); ?> <?php the_author_posts_link(); ?> &middot; <span class="date updated"><?php the_time(get_option('date_format')); ?></span></p>

So by the time all the edits are done, my single.php looks like this:

<?php get_header(); ?>

<section class="content">

	<?php get_template_part('inc/page-title'); ?>

	<div class="pad group">

		<?php while ( have_posts() ): the_post(); ?>
			<article <?php post_class(); ?>>
				<div class="post-inner group">

					<h1 class="post-title"><?php the_title(); ?></h1>
					<p class="post-byline"><?php _e('by','hueman'); ?> <span class="vcard author"><span class="fn"><?php the_author_posts_link(); ?></span></span> &middot; <span class="date updated"><?php the_time(get_option('date_format')); ?></span></p>

					<?php get_template_part('inc/post-formats'); ?>

					<div class="clear"></div>

					<div class="entry">
						<div class="entry-inner">
							<?php the_content(); ?>
							<?php wp_link_pages(array('before'=>'<div class="post-pages">'.__('Pages:','hueman'),'after'=>'</div>')); ?>
						</div>
						<div class="clear"></div>
					</div><!--/.entry-->

				</div><!--/.post-inner-->
			</article><!--/.post-->
		<?php endwhile; ?>

		<div class="clear"></div>

		<?php the_tags('<p class="post-tags"><span>'.__('Tags:','hueman').'</span> ','','</p>'); ?>

		<?php if ( !ot_get_option( 'author-bio' ) && get_the_author_meta( 'description' ) ): ?>
			<div class="author-bio">
				<div class="bio-avatar"><?php echo get_avatar(get_the_author_meta('user_email'),'128'); ?></div>
				<p class="bio-name"><?php the_author_meta('display_name'); ?></p>
				<p class="bio-desc"><?php the_author_meta('description'); ?></p>
				<div class="clear"></div>
			</div>
		<?php endif; ?>

		<?php if ( ot_get_option( 'post-nav' ) == 'content') { get_template_part('inc/post-nav'); } ?>

		<?php if ( ot_get_option( 'related-posts' ) != '1' ) { get_template_part('inc/related-posts'); } ?>

		<?php comments_template('/comments.php',true); ?>

	</div><!--/.pad-->

</section><!--/.content-->

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Everytime I update hueman to the newest version, these changes go away and I have to redo them. Can we get these lines coded into the theme by the theme author? Thank you.
