Perhaps you may have rsolved this issue, but if not, What you need to do is very simple.
Just do a stop and start of the netbackup process, that will refresh your Policy List. i.e
On your backup master server, do this as root:
#/usr/openv/netbackup/bin/goodies/netbackup stop
#/usr/openv/netbackup/bin/goodies/netbackup start
Go back to your Remote Console and launch the Console again and your scheduled backups in the night will run without that Policy. It's gone!
