No comments in Pages

Hello,

The comments section is not visible in pages, although the check box for showing comments in pages is checked.
Replacing the

<?php
// If comments are open or we have at least one comment, load up the comment template
if ( get_theme_mod( 'sparkling_page_comments' ) == 1 ) :
if ( comments_open() || '0' != get_comments_number() ) :
comments_template();
endif;
endif;
?>

part in page.php with <?php comments_template(); ?> makes the comments section visible. However, this time the show comments check box loses it’s functionality.
Any solutions?
