[Plugin: Yet Another Related Posts Plugin] How to remove Related Post Title

Hi, I am trying to remove Related post tiltle and I am using following code:
<?php related_posts($limit=5, $len=10, $before_related = ”, $before_title = ”, $after_title = ”, $before_post = ”, $after_post = ”, $show_pass_post = false, $show_excerpt = false); ?>

But it still shows the title.
