Remove the text box from featured slider

How do I remove the White text box with the orange, curved border that is visible on the featured slider on the home page of my site: https://saintbridget.org/

This is setup to be the background for text which goes over the images. But I won’t use any text so I want to remove the background (White text box with the orange, curved border) all together.
