On a tape containing duplicated saveset, from media mgmt window, it seems like there is no saveset dated on the time when duplicate ran.
When a saveset is duplicated, the duplicated saveset would have the same saveset ID, and timestamp as the original saveset.
Check NetVault log to find the timestamp and saveset ID of Phase 1 Backup.
