ZFS bug: zpool expandz says 16.0E, clearly wrong

I've stumbled across a curiosity with my zpool. The command 'zpool list'
states that the EXPANDZ property/value is 16.0E. This is clearly incorrect.
:)
The pool consist of a single RaidZ2 vdev of 6 drives, and two cache drives.
No log device. Executing 'zpool list -v' shows that each member of the
RaidZ2 has an 'EXPANDZ' value of '-', as expected. But the RaidZ2 itself,
and the pool, has a EXPANDZ value of 16.0E.
Each member of the RaidZ2 vdev is a GELI encrypted partition.

(It was built from 10-STABLE)
Once I discovered this curiosity I started a scrub, which is scheduled to
finish in about 7 hours from now. It seems to be done scanning the zpool
metadata and haven't repaired anything yet.
Output of zpool list, zpool list -v, zpool history and zfs list are
attached.
Anyone have any idea how to figure out what has happened here?
