post repeated in two column magazine theme

Hi all I have cooked uo a custom magazine theme and am now working out some of the kinks and bugs, one that I have recently noticed is that post from the bottom of column 1 are repeated at the top of column 2. This as I hope you can imagine is quite annoying.

This is the code that I am using for my homepage, I have looked through it and cannot see why this is hapening, so I was hoping that comeone from the community would be able to help me out.

<?php get_header(); ?>

	<div id="content">

<div id="feat_section">

	<?php if (have_posts()) : ?>

<!---FEATURE LOOP STARTS--->

<?php query_posts('cat=174&showposts=1');
$ids = array();
while (have_posts()) : the_post();
$ids[] = get_the_ID(); ?>

  <div class="feat_title">

                        <div class="feat_title">

                          </div>

<div class="post_author">
