Find this block in bender/functions.php:
foreach($c as $key => $value) {
?>
<li>
<a id="cat_<?php echo osc_esc_html($value['pk_i_id']);?>" href="<?php echo osc_esc_html(osc_update_search_url(array('sCategory'=> $value['pk_i_id'], 'iPage'=>null))); ?>">
<?php if(isset($current_category) && $current_category == $value['pk_i_id']){ echo '<strong>'.$value['s_name'].'</strong>'; }
else{ echo $value['s_name']; } ?>
</a>
</li>
<?php
}
Replace with:
foreach($c as $key => $value) {
?>
<li>
<a id="cat_<?php echo osc_esc_html($value['pk_i_id']);?>" href="<?php echo osc_esc_html(osc_update_search_url(array('sCategory'=> $value['pk_i_id'], 'iPage'=>null))); ?>">
<?php if(isset($current_category) && $current_category == $value['pk_i_id']){ echo '<strong>'.$value['s_name'] . ' (' . $value['i_num_items'] . ')</strong>'; }
else{ echo $value['s_name'] . ' (' . $value['i_num_items'] . ')'; } ?>
</a>
</li>
<?php
}
