I am using CSV upload and everything works good (with less than 70 products uploading), except when I wish to put quantity to zero for some products. When I upload CSV with 0 quantity, nothing happened. Quantity did not change but stays the same as before.
I do not want to disable them, I wish them to be visible because I will have them again on stock in future. If I am changing the quantity to number 1 or more, everything works well. Any idea?
