Controlling Jetpack subscriptions header

The header in my client’s Jetpack email alerts have a link in the header attached to her name. When clicked it goes to a error 404 page.

I’m wondering how to control the link in the header. On my site, clicking my name goes to author archives. But hers don’t and I’m wondering why. And where to make the changes.

Please let me know if this can be done.
Thanks!
