I have just bought a router for kids and configured parental controls right away.

I put down some URLs like Twitter and Facebook but when I try to access them through my kids' laptop it can still access them

Below is the snapshot of the settings

I also have set the time, as I thought the green means that the parental control will be available during the "green" time

and below is the URLs that are blocked in the parental controls

Do you guys have any solution on it? Thank you!
