query_posts issue

Hi,

I have a really weird issue at http://whetstoneinc.ca/ website. As you see under the section Whetstone Blog there are 2 posts showing.

It should show only 1 latest post and the code is :

<?php query_posts('posts_per_page=1'); ?>

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<h4><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h4> 

<?php the_advanced_excerpt('length=20'); ?>

<?php endwhile; else: ?>

<?php endif; ?>

<?php wp_reset_query(); ?>

The issue might be caused by the “What’s Wrong With Your CRM?” post, that is set as Sticky.

The interesting thing is that if I put
<?php query_posts('posts_per_page=3'); ?>

It shows 3 posts as it should. It’s only with number 1 that it’s glitching.

Any ideas how can I fix it?

Thanks,
Andrew
