template-tags.php issues?

So I just noticed that on my content single page when viewing an article, the template-tag says “author / date on date in category”.

it shows the date twice. I was using a child theme for this and was trying to get it to look like this.

Author posted on Date in Category.

<?php
/**
 * @package Expound
 */
?>

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

	<header class="entry-header">
		<h1 class="entry-title"><?php the_title(); ?></h1>

		<div class="entry-meta">
			<?php expound_posted_on(); ?><? echo " on ";?><?php expound_posted_in(); ?>
		</div><!-- .entry-meta -->
	</header><!-- .entry-header -->

	<div class="entry-content">
		<?php the_content(); ?>
		<?php
			wp_link_pages( array(
				'before' => '<div class="page-links">' . __( 'Pages:', 'expound' ),
				'after'  => '</div>',
			) );
		?>
	</div><!-- .entry-content -->

</article><!-- #post-## -->

That is the code that is in my child template-tag.php file. Any help?
