RMAN is not deleting archivelogs on standby

Hi Friends,
I have a stand alone 11.2.0.3 physical standby database.

Both the primary and standby are in sync. Both the primary and standby are using flash recovery area.

On PRIMARY:

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      +FRAGRP
db_recovery_file_dest_size           big integer 8G


On STANDBY
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      +FRAGRP
db_recovery_file_dest_size           big integer 8G


On Primary archivelog deletion policy is as follows:

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;


On Standby archivelog deletion policy is as follows:

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
