[EventCalendar] viewing category page with Version 3.1._pre11

[ejm]

I just installed Version 3.1._pre11 (but left 3.0.4 available by
renaming the folder) 3.1._pre11 seemed to be working correctly until I
tried viewing the event category page. Not all upcoming events
appeared. In fact, only one event from this month (that had already
taken place) appeared. No other events were listed.

This is what I have on my sidebar on the category section:

----------------------------------------------
<li id="categories"><h2><?php _e('categories '); ?></h2>
	<ul>
	<?php wp_list_cats('sort_column=name') ; ?>
	</ul>
</li>
------------------------------------------------

I have disabled 3.1._pre11 and re-enabled event calendar 3.04
