You will want to go into the templates (ie home.tpl.php) and remove the part where the total is displayed.
For example in home.tpl.php you should have the plugin to ddisplay the query which looks like this....
HTML Code:
{html_table_adv loop=$data cols=$cols table_attr='width="100%"'}
[[start_link]]<img src='[[image]]' border='0' alt='[[name]]' /></a> [[start_link]]<strong>[[name]]</strong></a>
([[total]])
<br />
[[subcats]]
{/html_table_adv}
simply remove the ([[total]]) so it looks like this.....
HTML Code:
{html_table_adv loop=$data cols=$cols table_attr='width="100%"'}
[[start_link]]<img src='[[image]]' border='0' alt='[[name]]' /></a> [[start_link]]<strong>[[name]]</strong></a>
<br />
[[subcats]]
{/html_table_adv}
