Woocommerce Out of Stock Not Showing

I have the woocommerce plugin. One of my items is a variation and I am out of stock on two of those items. The out of stock is not showing up on both the white and black medium shirt options. I have selected out of stock and but stock quantity at zero. But it’s still able to be purchased on the site. I have also gone onto woocommerce- settings- product – inventory and check hide out of stock items from the catalog. I have turned this option on and off and still nothing has changed. Any suggestions?
