Stock amount to updated after delete

[EIF]

A customer added, by accident, 3 orders with the same products. One order is paid and delivered, so I deleted the other two orders.
But after deleting the orders, the stock of these products is still the same. If I look in the stock overview, there are still products with status 'ordered', and because of that the products are not available for sale.

I think that before I deleted the order, had to change the status of those orders. But how can I fix the stock level at this point?

You could just go in and update your inventory on hand for those products, like you would if you received new shipments in.

Oh, I see. How stupid   
Not the stock amount I had to change by hand, but the field of the ordered amount (or however what the english translation is for it).

Thanks PolishedGeek!
