Remove Category-Name from Blogroll

Hi,

I have a blog with several authors and I want each of them to have an individual blogroll. So I created a category for each of them and implemented this code on author.php:

<?php $author = the_author();
		$array = get_bookmarks();
		wp_list_bookmarks(array( 'orderby'=>'name', 'order'=>'ASC', 'limit'=>-1, 'category'=>'', 'hide_invisible'=>1, 'show_updated'=>0, 'show_description'=>0, 'category_name'=>$author, 'echo'=>1, 'categorize'=>0, 'category_orderby'=>'', 'category_order'=>'', 'title_li'=>'', 'class'=>'', 'before'=>'<li>', 'after'=>'</li>', 'title_before'=>'', 'title_after'=>'', 'category_before'=>'<li class="invisible">', 'category_after'=>'</li>', 'between'=>'') ); ?>

And this is the result I get:

<ul>
<a>Herschel</a><li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
<li><a href="#">Link 3</a></li>
</ul>

Does somebdy know how to remove this category-name there. I have no idea anymore…

Please help me.
