Two things.
First,, you have not selected a header image, you have selected a WordPress site logo, and used that as a replacement for the site title.
If this is what you wanted, the problem is that the URL of the image selected is invalid (see link below)

If you actually wanted a header image, select one in Appearance > Header, and make sure you have not selected to hide the featured image in Customize > Visibility > Header area
