ReadyNAS RN314 on 6.9.2 - Encrypted volumes removed, key still required to boot

I recently went through rebuilding the volumes on my RN314.  I used my external enclosure to transfer the data to, then recreated the volume without encryption on the RN314.  I then copied the data back.  When that was complete, I recreated the volume on the external enclosure.  Both volumes were made without encryption.

I thought that when removing encryption from the volume that I would no longer need the key.  However, I get a message on the screen that the RN314 is waiting for the key to be inserted.  What exactly is it needing to decrypt?  Not one volume in the system has encryption anymore.  

Anyone ever see this or know what to do?

Thanks!
