DataGuard - Sequence No is not available in Standby site

Hi

I have just configured DataGuard (Oracle 12c  TNS for Linux: Version 12.2.0.1.0 - Production).

Problem is that sequence No. Is not showing in standby server.

SQL> select SEQUENCE#,APPLIED from v$archived_log  where SEQUENCE#=(select max(SEQUENCE#) from v$archived_log);

SEQUENCE# APPLIED

        27 NO

Standby Server
