wp_list_categories limit

Hi,

I’m having an issue with wp_list_categories – for some reason it is only returning 10 categoris – eventhough I am not specifyng a “number” in the query – my code is below:
<?php wp_list_categories('include=69,16,17,170,171,251,210,14,211,307,615&title_li=Quick Links'); ?>

Anyone have any ideas why this would be happening?
