Have tried all possible combinations I can come up with, but still haven't managed to solve this one

I'm on Joomla 3.9.14, VM 3.4.5 and CSVI 7.14.0 with updated plugins.
I need a list of all coupons used for a certain period. I chose the Virtuemart "Order" operation.
I only have these 3 fields :
virtuemart_order_id
discount_coupon
coupon_code
Still, each order appears on several lines (duplicates). I a customer ordered 10 products, the order appears on 10 lines.
I can see that this makes sense if I also chose to export data about the individual products, but this time I don't.

But what I want is obviously this :
Any ideas what could be wrong here?
Truly grateful for your help

Thanks
Best wishes
Peter
EDIT : I also attached the template I'm using in the example above
