Zero stock on attribute problem

so we have square set up with about 200 products. we are trying to link woocommerce to square and after some troubleshooting everything seems to be working properly except one thing. Shirt A comes in 2 colors, so 2 attributes in square and woocommerce. in square there is 5 red shirts and 0 blue shirts. on the website it shows that there is 5 red shirts and 5 blue shirts. the blue shirts can even be added to a cart and thus ordered. if in square i change the quantity of the blue shirts to anything besides 0, everything works perfect. this same problem occurs for every product with attributes where 1 or more attributes have 0 stock. any item with no attributes works fine with 0 stock.
