paginate_links Seperator showing last, how do i fix this?

I’m using paginate_links using this code

<?php
global $wp_query;

$big = 999999999; // need an unlikely integer

echo paginate_links( array(
	'base' => str_replace( $big, '%#%', get_pagenum_link( $big ) ),
	'format' => '?paged=%#%',
	'current' => max( 1, get_query_var('paged') ),
        'prev_text'    => __('&laquo; Previous'),
        'next_text'    => __('Next &raquo;'),
	'total' => $wp_query->max_num_pages

) );
?>

and it’s showing up like:
? Previous 1 2 3 4 5 6 9 Next ? …
with the separator dots outside of the nav
any ideas on what could be happening?
thank you.
