I've edited the debug message with the output from the right page this time (sorry).

On the page I'm calling:

<?php
   perch_blog_categories(array(
        'blog' => 'faqs',
    'cache' => false,
    'template' => 'category_list.html',
    ));    
?>

on the template 'category_list.html'

<perch:before>
<h3>Categories</h3>
<ul class="list-group">
</perch:before>
    <perch:if id="visible" value="0" match="eq">
        <li class="list-group-item">
        <a href="/news/category/<perch:category id="catSlug" type="slug" />">
            <perch:category id="catTitle" type="smarttext" />   
        </a>
    </li>
    </perch:if>
<perch:after></ul></perch:after>

The second blog was added at a later date. Could there be some residual data in the database that's having an affect?
