Gateway Network Policy Not working

I have enforced an IP to be blocked as part of Gateway Network policy. However , the IP is not being blocked.

The output for curl to trace url is below :-

warp=plus
gateway=off

The output from browser is given below :-

I have also enabled Network Firewall settings. Screenshot below.

However, I am unable to determine where I am going wrong. The trace url output shows gateway=off.

I am using $0 plan as of now.

What the logs say?
Check all DNS, Network and HTTP. There must be indication why such traffic is allowed.
