Acronis B&R 10. Recovering two MBRs (can't choose the second disk for the "disk 2 MBR"

Using Acronis B&R 10 enterprise. I made a full backup of a server that had two disks.

I need to recover that image to another server that has two disks. When I attempt a recovery, I am forced to choose "where" to recover to for both Disk 1 MBR and Disk 2 MBR. for Disk 1 it lets me choose the first disk on the new machines.

BUT

when I go to choose ('change') the second location to restore Disk 2 MBR to.....My second disk is greyed out.....(it was an option for the first MBR, but everything is greyed when attempting the same action for the second MBR)

both disks are exactly the same, in a brand new computer.

please help.
