Can't change my Shipping information

I recently updated my Apple ID with a new email address. However, I discovered that Apple is sending shipping updates to my old email address. I'm trying to update this info, but when navigating to apple.com/shop/account/home, then under Account Settings > Shipping > Contact information, nothing happens when I click the Edit button. I was able to successfully change this for my Apple ID, but for some reason, the Edit button under Shipping doesn't function.

Any help would be much appreciated. Thanks.
