Max capacity is listed as 16TB

I had an early model Drobo that I had originally set up with a disk pack as 16TB. I eventually migrated those disks to a 5D3. I currently have 5 3TB drives installed. Drobo Dashboard shows 10.84TB total capacity (which matches what the configurator shows for that setup.) In the Volumes panel, though, max capacity is 16TB. Do I need to reformat to increase the max capacity or is there something else I can do?

I’m pretty sure it takes a factory reset to change from 16TB max to the new max.
