Stats Section help

On the Stats section, i would like to set up something very similar to the demo, just 4 columns with a title and sub title. however, if you choose to make the type "custom" (which i think the demo was...) you have to add an image. I dont see any option to remove the image, and if you dont upload one, it still leaves a placeholder image. Is there a way to remove the image from the custom type? just want the text like the demo. Thanks!
