Stock Product not decreasing after changed status

Hi.
I am currently using HikaShop 1.6.0 version
And I think I found a bug which is quite dangerous for the site
When you give stock to a product, it decreases every time customer create a checkout on the frontend. On the backend, every order can be seen with their status, whether it's created, confirmed, shipped, etc. And when you changed the status from created to cancelled, the decreases stock will returned back, to the stock. So for example if an order with 3 product is cancelled, 3 products will be returned to database. The problem occur when the same order is activated again, from cancelled to created again. No product stock is decreasing from the database. So every time I changed the status to cancelled, it returns stock. But it doesn't do the same when I changed it into created status

Is it fixed in the 2.0.0 update?
