ZC 1.3.8a

I am running Checkout by Amazon and Google Checkout as addons to the other modules. In the admin - config I do have the out of stock to not be able to checkout. However, Checkout by Amazon is allowing customers to checkout more items than what is shown instock.

Google Checkout is abiding by the rule set and will not let anyone checkout till they correct the quantity.

Anyone know how to get the thing to follow the out of stock settings?
