blocked fool.com , cnn.com and rt.com as tests for blacklist. expected them to be blocked and show a site can't be reached .
Cleared browser caches, rebooted PC to see if there were lingering TTL's or IP address caches for these domains . Used different browsers still was able to access these sites
Please paste the output from
dig cnn.com @10.100.200.239

That's a blocked domain. NULL blocking mode. Pi-hole is blocking.
Note: cnn.com is not the same as www.cnn.com or ads.cnn.com or anything.cnn.com.
Dan . I can see that its blocking . If I do 'dig' on cnn.com , rt.com or any other blacklisted domains , I do see that they return 0.0.0.0 . AND Yet when I used browser to access the blocked domains they were accessible .. been banging my head for 3 hours now ...
dig output demonstrates Pi-hole to be blocking as expected.
If your browser still resolves, it's very likely specific to that browser - either a a caching issue or a browser setting.
Try clearing your browser's cache to wipe out any known IP's for previously resolved hostnames, and disable the DNS-over-HTTPS (DoH) and "Help resolve naviagtion errors by using a Google DNS web service" features in your browser.
