My non-cdb 12.2 database is noarchivelog mode.
Also, RMAN is set: CONFIGURE CONTROLFILE AUTOBACKUP OFF;
When mounted, I did back it up. As a result.
RMAN> list backup summary;
List of Backups

Key TY LV S Device Type Completion Time #Pieces #Copies Compressed Tag

2 B F A DISK 27-JUN-19 1 1 NO BEFORE IMPORT
After some time I decided to restore this database.
I set this database in nomount state, restore controlfile from backupset 2, then I mount it and I restore the database.
When I now list my backups, there is only one file being shown (backupset 1). The one with controlfile is missing (backupset 2) though it is still physically on the backup device.

Why is that, and does it mean I cannot repeat database restoration the same way I did for the very first time described above?
