When trying to fetch the filesystem type for a given volume, I always get error when using it with format.

Please note that I have used whitespace for "Filesystem Type" as per the documentation but it just doesn't work. Please update the documentation with the correct usage.

$ doctlro compute volume get "<volume_id>" --format "Name,Size,Region,Filesystem Type,DropletIDs"

Error: unknown column "FilesystemType"
