IDSAFE Does Not Work on PFCU's Website

IDSAFE does not work with Pentagon Federal Credit Union's (PFCU) website.  It will not fill-in your login ID, but if you fill that in and enter, it will fill-in the password field.  The URL for the login ID is https://www.penfed.org/.  The URL for the password is https://online2.penfed.org/PenFedOnline/Forms/Security/LogonPassword.aspx.  How do I get it to work for both fields?
