External Drive Capacity Not Added to Internal Capacity on Dashboard

In prior OS versions, when I connected my external drives to the WD EX4100 NAS, their capacity was added to the capacity showing on the main web dashboard. Now, it isn’t added to the capacity. It’s only showing the internal capacity. Is that working as designed or should it actually be adding the two together to give me total capacity?

@adamv76 That is correct.
My Cloud OS 5 doesn’t add the capacity of the external USB drive to the capacity of the device as it did in My Cloud OS 3.
