Ubuntu version in Details (in System Settings) says 16.10 not 17.04

The Ubuntu version in the Details section of System Settings reads 16.10 when it should read 17.04.

I reported this for Ubuntu 16.10 too, was fixed promptly! https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1581192
