Snippet being rendered outside column shortcode

Here is the code I use on home page:

[one_third_last]
<h5 class="homepage">Other Recent News</h5>
[blog_list thumb="small" showposts="3" category_in= "46" disable="content,meta,more"]
[random_posts title="Did you read these stories?" quantity_of_posts="2" Style_sra="3" AutoUpdate="1" Updating_Time="5"]
<h5 class="homepage">Recent Comments</h5>
[php snippet=3]
[/one_third_last]

Here is my snippet:
<?php if(function_exists('jme_display_comments')) { jme_display_comments( array( 1 => 1, 2 => 40, 9 => 1, 3 => '<h3><a href="%PERMALINK%">%POSTTITLE%</a></h3>"%COMMENT%..."'));} ?>

It works, but here is the HTML output:

<div class="one_third last">
<h5 class="homepage">Other Recent News</h5>
<ul class="post_list small_post_list">
<div class="widget spider_random_article">
<script type="text/javascript">
<div id="randarticle_0" style="">
</div>
<h5 class="homepage">Recent Comments</h5>
<ul class="customized-recent-comments">
<li class="recentcomment">
</ul>

The homepage code has [php snippet=3] inside the [one_third] column tags but the HTML is rendered with the snippet appearing outside/after the closing <div> of the column.

Any idea why – and how can I fix it? If you want to view the page it’s here: dev.henleyherald.com – you can see how the snippet should be lined up in the right hand third column but is wrapping across the whole screen.
