Ghost update is called that because the status changes from "Submitted" to "Application/profile updated", before you click on the application. Once you click it, nothing has changed in the application status (you've been visited by a ghost). This is why we call it a ghost update. As soon as you click it, your status goes back to "Submitted".
Did you also get an email that your profile is updated or was it only when you logged in that you saw?
