Quantity is not matching with Ali express website.

I am facing problem with quantity, it’s not same on products as Ali express. I am going to send you example product links so please take a look at this problem and give me solution, even i have tried synchronization but it doesn’t change.

My Website Link:- https://millenniumstuff.com/product/folding-mobile-phone-holder-stand-aluminum-alloy-invisible-portable-stand/
Ali Express site link:- https://ar.aliexpress.com/item/1005003532470648.html ( Please check black color )

Check the quantity for both products.

Thanks
