To much page are displayes

Hi, I’ve put this code to display pagenavi in a template page :

<div align="center" name="nav">
	<?php
		if ( function_exists( 'wp_pagenavi' ) ) {
			wp_pagenavi( array( 'query' => $loop ) );
			wp_reset_postdata(); }
	?>
</div>

But, in the pagenavi, I can see 30 pages, but I’ve less pages that are displayed ..
