Bareos won't use both tape drives in autoloader

I'm using a Neoseries T24 (Flexstor II) autoloader with two drives. I have tapes (11 of them) in a pool labeled 'Full'.

When I run two jobs, both for the 'Full' pool, they will wait in sequence so they can both use the same drive (0) instead of one running on drive 0 and one running on drive 1.

Is it possible to have any tape from the Full pool an available drive in the autoloader so that two jobs can be run simultaneously?

Do two SD daemons need to be running?
