WP-PageNavi double navigation

Hi,

I replaced default navigation links with WP-PageNavi navigation.

Default code

<?php if ( get_next_posts_link() ) : ?>
			<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'tesseract' ) ); ?></div>
			<?php endif; ?>

			<?php if ( get_previous_posts_link() ) : ?>
			<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">&rarr;</span>', 'tesseract' ) ); ?></div>
			<?php endif; ?>

Replaced it with

<?php if ( get_next_posts_link() ) : ?>
			<?php wp_pagenavi(); ?>
			<?php endif; ?>

			<?php if ( get_previous_posts_link() ) : ?>
			<?php wp_pagenavi(); ?>
			<?php endif; ?>

But one page 2+ I get double navigation. One the last page and the first page it’s fine. What do I have to change in the code?

Thanks.
