Error – Variation Swatches for WooCommerce

Good morning,

I installed the Variation Swatches for WooCommerce plugin so that the sizes and colors of the products would disappear as the stock reaches “0”.
That said, lately I’ve noticed that for some products this doesn’t happen. In other words, the product goes to “0” in a certain size and that same size isn’t hidden (it tells you that the stock is at 0 and you can’t buy it). It turns out that in most products the size with 0 stock is hidden and doesn’t mislead the customer.
Example: https://neverland.com.pt/produto/t-shirt-maxmara-6/
in this link you can see that the product in size “M” is at 0 and has not been hidden.
Can anyone help me solve this problem?
