the_author template tag does not work on certain pages

Hi,
I’ve created a category-XX.php and placed it but my the_author tag does not seem to show. However on other pages it shows.

check this out: http://beta.boontan.net/category/reviews/
I’d like it to look like “http://beta.boontan.net/anime-review/”

browse the other categories like Anime updates(under Navbar)and you can see the_author tag there.

This is my code:

<?php get_header();
?>

<div id="content">

		<div class="archive">
			<p /><h2>Reviews</h2>
			<?php $recent = new WP_Query("cat=17&showposts=-1&orderby=title&order=asc"); while($recent->have_posts()) : $recent->the_post();?>

		<?php the_title(); ?> <a>"> - <?php the_author(); ?> </a>

			<?php endwhile; ?>

	</div>

<?php include(TEMPLATEPATH."/sidebar.php");?>

</div>

<!-- The main column ends  -->

<?php get_footer(); ?>
