Stock 1 considerer 0

Hello,

For the past few days, I've been experiencing a strange issue. Products that have a stock of 1 are considered out of stock. On the product page, they appear as in stock, but when added to the cart, they show as out of stock.

The last extension I installed was AJAX Quick Checkout. I removed the extension, but the issue persists.

Do you have any idea where the problem might be?

Thank you!

opencart 3.0.3.8

It would be great if you could share the front-end URL of your website so we can replicate the issue. As per the Default Opencart functionality, there is no such feature or issue available, so there might be a chance that you are using some module that is deducting the quantity of the product when the same is added into the cart.

So please share the screenshot of the Admin Product Quantity as well, it will help to check the issue.
