Snapcentre and Oracle Standby Databases

We are trying to create a backup of an Oracle Dataguard Standby database with Snapcentre 4.4. When we create the offline schedule with 'Shutdown' mode when we run it it throws this message:

Activity 'Discovering Oracle Database Files' failed with error: Discovery failed for object MYDB with error PL-SCO-20006: Discovery of database files failed for database MYDB on host myhost with error PL-SCO-20035: OFFLINESHUTDOWN DATA backup is not supported for Data Guard standby database.. Activity 'Finalizing Oracle Database Backup' failed with error: PostBackupActivity failedPL-SCO-20032: postBackup operation failed with error: PL-SCO-20035: OFFLINESHUTDOWN DATA backup is not supported for Data Guard standby database.

The guide for Snapcentre 4.4 states:

Oracle Data Guard standby

You can create only offline (mount or shutdown) backups of Data Guard standby databases. Archive log-only backup or full backup is not supported.

So why would this not work? I did see this KB and tried the steps but same error.
