Unable to expand array on StoreEasy 1840

[ac4378]

We recently replaced the P822 controller on a StoreEasy 1840 and all arrays came back up to normal (no data loss), however, I am now unable to expand any of the arrays using a brand new drive that we just added.

All drives on the server including the new one are genuine HPE parts and they are all the exact same model.

From ACU, I click on the array, Expand Array button, select the new drive, and then click Save but I immediately get this error "The operation has failed with an unknown error. Please restart the application and attempt the operation again." and the expansion never takes place. I get this whether I run ACU from Windows itself or before (by pressing F5 during server boot).

Here are the controller details:
