Help getting rid of unwanted group by

Question

I'm working on Discoverer Desktop 10.1.2.1 with Oracle Database 10.2.0.4.0.
If I'm creating a summary type report and include items
item_number
onhand - sum
cost - detail
I'll get sql (Vew/Sql Inspector) like the following:
select item_number, cost, sum(onhand)
from <whatever>
group by item_number, cost
Now, I save my report and realize that I wanted to include cost - sum rather than cost - detail. So I remove cost - detail as a selected item and replace it with cost - sum. Now I check my sql (Vew/Sql Inspector) and it's still grouping by item_number, cost.
select item_number, cost, sum(onhand), sum(cost)
from <whatever>
group by item_number, cost
Any ideas what might be causing this behaviour?

Thanks John and Michael - I was able to reproduce the issue with a very simple test case. Now all I need is permission from my higher-ups to author an SR.
1) Create a custom folder in Admin
select inventory_item_id
,subinventory_code
,transaction_quantity
from inv.mtl_material_transactions
where inventory_item_id = 127680
2) Create a new report in Desktop with items
Inventory Item Id
Subinventory Code
Transaction Quantity - Detail
3) Run and save the report and view the SQL Inspector - the query is accurate
4) Remove Transaction Quantity - Detail and replace with Transaction Quantity - Sum
5) Run the report - the query is inaccurately selecting and grouping by Transaction Quantity - Detail
6) Open the report in Discoverer Plus (10.1.2.2) - the results are the same, the query is inaccurate
7) Start over in Discoverer Plus (10.1.2.2) and perform steps 2,3,4, the query is accurate, Transaction Quantity - Detail is removed.
