How to remove 'currently unavailable' on the main shop page, but keep on the specific product page

Site URL: https://www.sumofeight.com/

When a product on my shop is sold out, on both the product page and the main shop page a 'currently unavailable' message appears. I like it on the product page, but on the main product shop page its bold and I dislike it being there. Does anyone know a way of turning it off but not the message on the specific product page? 

Thank you!

Ps. Right now on the website there is still items available, so this message doesn't appear, but products are close to selling out so I am planning in advance!
