zfs partition wrongly shows occupying the whole disk

gparted_sshot

After making a zfs partition, gparted wrongly shows it occupying the whole disk, see attached screen shot.

However, both parted and fdisk are right:

# parted -l /dev/sda

Partition table entries are not in disk order.

I know that partitions are not in order, but is that important for this issue?

I'm using the gentoo partition to operate gparted. And it's built like so (flags are gentoo default):

All the partitions, including zfs, are operating normally:

# zpool status
  pool: zmac
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
   still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
   the pool may no longer be accessible by software that does not support
   the features. See zpool-features(5) for details.
  scan: none requested
config:

   NAME        STATE     READ WRITE CKSUM
   zmac        ONLINE       0     0     0
