Header search turns up a listing that looks like blog posts

Hello! When you search for something on our website using the header search bar, it returns results in a list, rather than in a product style grid. 

I've changed the settings in the theme to Icon|Search Products Only, but its still showing the list, which looks a lot like blog posts instead of products and its confusing to my customers. 

Let me know how I can solve this issue. 

Thank you!
