I knew that problem. I've fixed it in my themes. Check this product http://panda2.sunnytoo.com/en/home/12-23-casual-simple-t-shirt-solid-round-neck.html#/28-size-xl 

It only has 2 items in stock.

It's a tough work to fix the problem, requires a lot of modifications. Hope prestashop team can fix it soon. Your site is under maintenance, so I don't which theme your are using, but I guess you are not running on the Classic theme, so you can let your theme's developers to know the problem to see if they can fix the problem.

Thanks for your response @tantan199

i will contact our theme dev.

Can you share  any idea about how to fix this problem as prestashop dev.

Quite a lot modifications, unable to share them our here.  And my solution is not perfect, it's for customer side, hope prestashop team can add the same restrictions to server side.
