Data does not appearing in the table

why the data not appearing in the table ( qty field),i just see the total qty , you can see picture to take an idea

res = frappe.db.sql(f"""SELECT 
    i.item_code,
    sii.qty as qty,
     b.actual_qty
FROM (
select 

item_code
from `tabItem`
group by item_code
) i

left join  (

select 

item_code,
sum(actual_qty) as actual_qty

from `tabBin` 
group by item_code
) b on b.item_code = i.item_code 


left join (

select 

item_code,
sum(qty) as qty

from  `tabSales Invoice Item`

group by item_code 

) sii on sii.item_code = i.item_code

GROUP BY

sii.item_code,b.item_code
   
   """, as_dict=True,debug=True)

result = res
