我怎么加在SQL上，所以它不会加倍，因为分组

Question

当我运行程序时，数字的结果取而代之的是将数字合并，并使数字成许多结果。

SELECT pengiriman_supply.po_nomor
    , data_supplier.nama_supplier
    , data_barang.nama_barang,
((sum(pengiriman_supply.jumlah))-(ifnull(masuk.terima,0))) as total 
FROM pengiriman_supply INNER JOIN data_supplier ON pengiriman_supply.idsupplier = data_supplier.id_supplier 
INNER JOIN data_barang ON pengiriman_supply.idbarang = data_barang.idbarang 
left JOIN masuk on masuk.refrence = pengiriman_supply.po_nomor 
where pengiriman_supply.tanggal between date_sub(curdate(), interval 120 day) and curdate() 
group by pengiriman_supply.po_nomor
ORDER BY pengiriman_supply.po_nomor desc;

结果是这个 enter image description here
