I am facing a problem on my Magento version 18.104.22.168. Whenever I save product on backend, if I haven't changed quantity field, qty value resets to 0 even though value was > 0. If I change value of quantity to something else prior on saving product, value updates successfully which I found very odd.
The stock status remain "In stock" which causes confusion to clients because products are showing in stock on frontend, but when customer click add to cart warning appears that says, "there is not enough stock for this purchase".
Any suggestions for this debug will be highly appreciated, we have reset a huge amount of products prior to noticing that stock was getting reset which created a bit of a chaos.
Thanks in advance.
