Hide product short description excerpt from products-category page

I created pages where I simply input my products-category slug and it displays that category’s products.

However, there is a long excerpt of the short description and I would like only the product image and the product title to be displayed.

Tried via functions.php as well as CSS but without luck.

Ideas?

Thank you in advance.
