I think thet I found solution form my problem…
In backend all acf meta box have class “postbox”. But they should have class “postbox acf-postbox”.
So in functions.php I added:
//acf
// fix for ACF PRO version 5.8.1
add_filter('admin_footer', function(){
echo '<script type="text/javascript">jQuery(".postbox").addClass("acf-postbox");</script>';
});
//end
