Chrome white list

I added 2 sites to the Chrome Lockdown > Allowed Sites and enabled.
This had no effect on Chrome I could browse anywhere. Also other configuration not enforced like Chrome Lockdown > General > No Omnibox
????
Thanks

Update - didn't change anything but on the second reboot now sites are blocked but omnisearch is still not.

This issue has been forwarded to a technical engineer. In the in interim, you can go to Chrome > Settings > Advanced Settings > Privacy and disable the "Use a prediction service to help complete searches and URLs typed in the address bar" option.
