Only one post showing in the loop when there should be more

I created a custom archive template and now am having trouble with the loop. Even though I have two posts, only one is displaying.

Here is my code for the loop:

<?php /* Start the Loop. */ ?>
<?php while (have_posts()) : the_post(); ?>
		<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
            <?php if ( has_post_thumbnail()) : ?>
               <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>" >
               <?php the_post_thumbnail(); ?>
               </a>
 			<?php endif; ?>
            <h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>
				<div class="entry-utility">
				<?php edit_post_link( __( 'Edit', 'twentyten' ), '<span class="edit-link">', '</span>' ); ?>
			</div><!-- .entry-utility -->
		</div><!-- #post-## -->
<?php endwhile; /*End the Loop */ ?>

Here is the archive page: http://www.southernresorts.com/southern-perks/

I don’t think this has anything to do with it, but the posts displaying are CPTs I made with the Custom Post Type UI plugin.
