Remove "Show Post Counts" from Tag Drop Down List

I’m using the following script to generate a tag drop down list

<select name=”tag-dropdown” menu class=”jumpmenu” onchange=”document.location.href=this.options[this.selectedIndex].value;”>
<option value=”#”>Choose a Topic</option>
<?php dropdown_tag_cloud(‘number=0&order=asc’); ?>
</select>

on my site at https://tinyhousereport.com

I need to remove the post counts from the drop down list but can’t seem to figure it how to do it.

Thanks!
