I'll take a look !
ETA:
open the file BoardNews.block.php (/subs/spblocks) on line 262 find:
$context['sp_boardNews_page_index'] = constructPageIndex($current_url . 'news' . $id . '=%1$d', $start, $limit, $per_page, false);
$context['sp_boardNews_page_index'] = constructPageIndex($current_url . 'news' . $id . '=%1$d', $start, $limit, $per_page, true);
So change that last false to a true
