perch_blog_custom filtering

 <?php    
    $opts = array(
    'category' => array('sue' , 'paul'), 'category-match' => 'all','sort'=>'postDateTime','sort-order'=>'DESC','template'=>'blog/latest-blogs.html');
    perch_blog_custom($opts);  ?>

Above is what I now have. I have one post tagged with both the 'sue' and 'paul' categories. With the above I get no posts. 'category-match' => 'all' , I get the post tagged with both tags and those with either. Is my syntax wrong?

This did not make any difference.

SELECT SQL_CALC_FOUND_ROWS DISTINCT tbl.* FROM ( SELECT idx.itemID, main.*, idx2.indexValue as sortval FROM perch2_news_index idx JOIN perch2_news_posts main ON idx.itemID=main.postID AND idx.itemKey='postID' JOIN perch2_news_index idx2 ON idx.itemID=idx2.itemID AND idx.itemKey='postID' AND idx2.indexKey='postDateTime' WHERE 1=1 AND ((idx.indexKey='postDateTime' AND (idx.indexValue >= '2015-01-01' AND idx.indexValue <= '2015-12-31'))) AND idx.itemID=idx2.itemID AND idx.itemKey=idx2.itemKey GROUP BY idx.itemID ) as tbl WHERE (postStatus='Published' AND postDateTime<='2015-04-02 13:48:00' ) GROUP BY itemID ORDER BY sortval DESC LIMIT 0, 10
SELECT FOUND_ROWS() AS `count`

What should I check?
