Steps to reproduce the problem:
1. Wallpaper was pushed through admin console in May 2018 through Device Management/Chrome/User Settings/Wallpaper
2. Wallpaper was removed (use Inherited) in August 2018.
3. Policy does not get removed from the device, but Chrome OS thinks there is no policy.  See screen shots:

What is the expected behavior?
Policy says "Not Set" so it should allow the user to change the wallpaper.

What went wrong?
Users can't change their wallpaper after being pushed a wallpaper. Does not affect everyone. Of our approximately 2000 devices, I'm guessing 1500 have the problem.

Did this work before? Yes 66-ish?

Some other users have reported this on GSFE community, but it has not been wide spread. Only way I have found to fix is to wipe the device.

v67 is where we first noticed it in August. Even on v69 now, it still seems to be broken.
