My Cloud Mirror 6TB Raid not rebuidling after new drive insert

Hello. In December 2019 one drive in the two drive failed. I replaced it with exact replica. the Raid Rebuild is set to Auto. This is Middle of February 2020. The Rebuilding hasn’t even started!!

I have tried: (1) Reboot, (2) Complete power down and restart (3) System Only Restore using the Utilities menu and (4) Reset using the small clip and inserting in the Reset Hole at the back.

So far no success

Any guidance, help, suggestions will be greatly appreciated from community members.
