Badge shows but above image instead of on.

I was able to get it to sort of work via line you asked we place in the CSS, however, it does not work well.

https://shakespearencompany.com/product-category/womens/ shows it perfectly fine, however going into the product itself the sold out icon is not on the image and is instead floating above the picture as seen here https://shakespearencompany.com/product/mid-century-bangle/
