+editemails only allows me to confirm one address

When I sent in my GPG key, launchpad noticed that it had several email addresses associated with it that it did not know about. I was then directed to https://launchpad.net/people/hypatia/+editemails to confirm them for launchpad if I wished.

I am presented with four email addresses and a *radio button* rather than series of checkboxes. I can therefore only confirm one of the four addresses given.
