After RSVP and show who is attending, user links to bad URL

When I rsvp to an event and click on "show who's attending" - I see myself. When I click on it, I go to: http://hmcountryclub.com/author/esarkis/ which is an invalid page. I'd like to remove the link (or have it properly link to the member page). Help is appreciated!
Thank you,
Emily
