Duplicate Comment Box

I'm seeing an issue w/ a duplicate comment box when choosing anything besides the default wordpress comment box. I'd like to not see the additional comment box when choosing FB or Twitter etc..

Here is my theme code where I entered the hooks for the plugin.

if ( get_option('comment_registration') && !$user_ID ) : ?>

<p><?php printf( __('You must be %s logged in %s to comment.', THEME_NAME), '', ''); ?></p>

<?php else : ?>

<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="PostCommentForm" class="comment-form">
<div><?php do_action('comment_form_before', $post->ID); ?></div>
<?php if ( !$user_ID ) : ?>

<label class="overlabel" for="author"><?php _e('Name', THEME_NAME); ?> *</label>
<input type="text" class="textInput" name="author" id="author" value="<?php echo $comment_author; ?>" tabindex="1" />
<label class="overlabel" for="email"><?php _e('Email', THEME_NAME); ?> *</label>
<input type="text" class="textInput" name="email" id="email" value="<?php echo $comment_author_email; ?>" tabindex="2" />
<label class="overlabel" for="url"><?php _e('Website', THEME_NAME); ?></label>
<input type="text" class="textInput" name="url" id="url" value="<?php echo $comment_author_url; ?>" tabindex="3" />

<?php endif; ?>
<label class="overlabel for-comment<?php if ( $user_ID ) { echo ' loggedIn'; } ?>" for="comment"><?php _e('Comment', THEME_NAME); ?></label>
<textarea class="textInput commentTextarea" name="comment" id="comment" cols="50" rows="12" tabindex="4"></textarea>
<div><button type="submit" class="btn"><span><?php _e('Add Comment', THEME_NAME); ?></span></button><?php comment_id_fields(); ?></div>


endif; // If registration required and not logged in ?>
<div><?php do_action('comment_form_after', $post->ID); ?></div>

</div><!-- END id=Respond -->[/code]
