[keycloak-user] Unable to update user account

In realm settings, I have enabled email as username and registered a user. However on "/auth/realms/master/account" page when I am trying to update any details of the user, it's throwing an error "Please specify username." Please note this is not displaying the username field on page when I enable email as username. Is it some kind of a bug in keycloak 3.2.1? Thanks and Regards, Krishna Kuntala
