RMAN RESTORE error after fresh full backup

Hi,
I am restoring to same database after a fresh full backup (10-minutes old). I decided to test if backups are okay before continuing but was astounded to get the error below

RMAN> RESTORE DATABASE FROM TAG T1 PREVIEW;

RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 32 found to restore
....                                                                   31
....                                                             (all in between)
....                                                                   2
RMAN-06023: no backup or copy of datafile 1 found to restore

older (last week's) Backups have been created in a parent folder. The other backups (in parent folder) which are a few days old work just fine. It was not me who created the backups in the parent folder but I have the script and it is similar in mine except for location. I chose a subfolder as to not get confused.
