{has_category} conditional placeholder not working on subsite

This code works on my main site but not on my subsite (in my multisite install). Any ideas?

<div class="cma-cal">
[events_list blog=1 limit="10"]#_EVENTDATES<br />{has_category_66}Album Release: {/has_category_66} #_EVENTLINK<br/>[/events_list]
</div><br />
<a href="http://www.cmaworld.com/calendar">Click for full calendar of events</a>
