download categories in e_upload.php file

[Jimmi08]

I have tree of download categories:

But upload categories display just this:

My USER_CLASS_LIST is 253,254,250,251,0

file e_upload.php in download plugin:

This is correct:
$qry = "SELECT download_category_id,download_category_name,download_category_parent FROM #download_category WHERE download_category_class IN (".USERCLASS_LIST.") ORDER BY download_category_order, download_category_parent";

retrieve() is correct
compile() looks correct too (all 8 records in tree)

but this code returs only 3 records:

  	foreach($ret as $k=>$v)
	    {
	        $id = $v['download_category_name'];
	        foreach($v['download_category_sub'] as $row)
	        {
	            $id2 = $row['download_category_name'];
		        $arr[$id] = array('download__'.$row['download_category_id']=>$id2);
	            if(!empty($row['download_category_sub']))
	            {
					foreach($row['download_category_sub'] as $key=>$val)
					{
						$subid = $val['download_category_name'];
						$arr[$id][$subid] = array('download__'.$val['download_category_id']=>$subid);
					}
	            }

	        }

	    }
