Pi Hole Apparently Not Set Up Correctly

Very new NOOB here, so apologies for a question that has already been asked multiple time, but in looking for past posts, I didn't really understand the solutions well enough to determine my problem.

Bottom line, using the CNN site, I am still seeing ads.

When I ssh to the Raspberry PI url, I get the following nslookup result, which I think indicates that everything is setup correctly?

installed on a Zero 2W board, with Orbi Router.

Expected Behaviour:

I would anticipate not seeing ads in CNN.COM if this PI was working correctly

Actual Behaviour:

I see many ads on CNN.COM

Sounds like ads are leaking in via IPv6 DNS server(s) supplied by your router via "IPv6 Router Advertisement".
You should check what DNS server(s) is/are configured on the devices that are still showing ads.
If any of them isn't Pi-holed, ads will leak in especially bc IPv6 DNS is preferred over IPv4 DNS for most implementations.
