I have set up time limits for a number of devices in our household per photo attached but they don't seem to work. The router Archer VR1600v. Can you please help.

For the Parental Controls to function based on the instructions you've set, you need to ensure first that the Time Settings match your local time. Try to go to Advanced > System Tools > Time Settings to ensure that the time zone and date are correct.
The next thing you need to check is the restriction policy.
