how to clean up archive logs at primary side which have been applied and backed up on standby side

Our DataGuard 12.1. is running on Windows. Backup of database and archivelogs are done at standby side to disk with rman. Catalog is stored in an extra database.. Now I have the Problem to cleanup the already applied and backed up Archivelog files at the Primary side of the DataGuard.

We changed the backup using rman, from "to tape" with NetBackup to "to disk".
Now the Statement at the Primary side:
delete archivelog all backed up 1 times to sbt_tape;
was modified to:
delete archivelog all backed up 1 times to disk;
But this Statement doesn't work. We get the message:
RMAN-08138: WARNING: archived log not deleted - must create more backups
