RMAN problem after Duplicate

I duplicated a production database using RMAN. I have done this many times. EXCEPT, this time I forgot to issue a RESET DATABASE for the duplicated database. My backups ran last night for both production and the duplicated database. The backup for the duplicated database failed with this error:

RMAN-20003: target database incarnation not found in recovery catalog

So, I connected via RMAN, issued the RESET DATABASE command and ran the backup.

Now, when I try to reference my duplicate database in RMAN, I get the following:

RMAN-20005 target database name is ambiguous

If I try to reference my production database in RMAN, I get the following:

RMAN-20003: target database incarnation not found in recovery catalog

Oracle support is recommending that I used SET DBID to duplicate production again. I am worried that my production backups may be useless, or worse - that when I duplicate the database I'll trash my production db. Anybody ever been here before?

Thanks,
