Customers can put MORE than current inventory in cart?

[#1]

On the Square website customers can put MORE than the amount of inventory in their cart.  How do I prevent this?

I put 4 in the inventory of an item, but when I go to the website I can choose more than that amount.

HI, how do you have track stock setup?

For reference, this is how Track Stock displays.

For reference, this is how the Stock column displays for unlimited inventory.
