Hello,

Your issue has been solved. Actually, you have not enable the stock management for the product, I have activated and follow the steps mentioned here in the theme documentation:

It is necessary to enable “Manage stock” in the product, fill the “Stock quantity” field out, and insert the initial quantity.
