Filter Gltich on variation Stock

Hi Support Team,

I need help regarding the filter functionality actually I’m using your plugin on my wordpress website. Here is the category page link https://giostockings.com/product-category/limited-edition/
Everything is working fine. I’m getting issues while filtering the products I mean when I’m filtering the products it returns out-of-stock product also. For Example: If I’ll choose ‘8.5’ size from the ‘Product Size’ filter it returns all the products with the 8.5 variations even the variation are out of stock.

I set this filter https://giostockings.com/product-category/limited-edition/?size=8-5 it returns this product also but the filtered variation is out of stock https://giostockings.com/product/mysterious-mulberry-limited-edition-fully-fashioned-nashville-heel-stockings/

I want only in-stock variations product in filtered products.
