category page incorrect h1

I find that the h1 of my category pages have unwanted text in the h1 title. Following the correct category name unwanted text this is. I have two categories one shows category title and blog title in the same h1, the other category title and author username in the same h1.

Example:
While “Title” is my correct category name.
correct -> <h1>Title</h1>
incorrect category 1 -> <h1>TitleBlog_Title</h1>
incorrect category 2 -> <h1>TitleAuthor</h1>

Like they are pulling something “too much” in their tittles, would seem like there’s a closing bracket missing somewhere. However i can’t spot it or understand what else could it be.

Here is my single.php in case it helps at all

<?php get_header(); ?>

<div id="middlecontent">

<?php theme_options_show_breadcrumbs(); ?>

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

    <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

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

     <div class="bylines">

          <?php if (!get_theme_option('bylines-hide-date')) { the_time('F j, Y'); } 

   if (!get_theme_option('bylines-hide-author')) { ?> by <?php the_author_posts_link(); }  edit_post_link(' (Edit)', '', ''); ?>

     </div>

      <?php the_content();?>

<div class="moreinfo"><?php if (!get_theme_option('bylines-hide-category')) { ?> posted in <?php the_category(', '); } ?> ?  <a href="<?php the_permalink(); ?>#comments">   <?php comments_number(); ?></a></div>

        <?php endwhile; else: ?>

	<p><?php _e('Sorry, no posts matched your criteria.'); ?></p><?php endif; ?>

     </div>

  <?php comments_template(); // Get comments template ?>

</div><!-- Middle Content  -->

<?php get_footer(); ?>

Thank you in advance
