Woo Commerce Header image problem


I just in the Woocommerce pages I can’t edit the header image. I tried to edit it on the customizer, but even though it said it was changing it, it wouldn’t. I’m stuck with the default header image for it.
My website is www.samdunbavin.com, the Woo Commerce part is www.samdunbavin.com/shop/
