CSS issue for stock status on few products only

Hi team,

I see a CSS issue on the product grid on the shop page for some product stock status. When you hover over the product, the stock status shows and disappears. Although this is happening only with some products.

e.g., go to this link: https://corporatespec.com/shop/page/8/
And see this product: https://prnt.sc/ceeUKBODGwKR

Thanks!
