Join Problem

Sir I have these codes

SELECT distinct T1."DocDate",
T1."DocNum",
T1."CardCode",
T1."CardName",
--T2."Quantity",
T0."Debit",
T0."Credit"
	
from
	JDT1 T0
	inner join OPCH T1 ON T0."TransId" = T1."TransId" AND T0."TransType" = 18
  inner join PCH1 T2 ON T2."DocEntry" = T1."DocEntry"
  where T0."RefDate"='2021-09-16'
  and T1."DocNum" =353
  and (T0."Debit"<>0 or T0."Credit"<>0)
  and left(T1."CardCode",1)='V'
  and T1."CANCELED"='N'
  order by T1."DocDate",T1."DocNum"

The code work fine but When add this column

T2."Quantity",

The every row appear as double like shown here

Please help me how to get single records.
