Static URL filter is not blocking

I have enabled the web filter feature in feature select

I have added a number of domains to the web filter

I have enabled web filter to a policy web traffic passes through

I have enabled SSL inspection

But still, the web pages are not blocked.

I have also tried none https sites and still, the websites are not blocked.

I assume I do not need a valid subscription of any kind to manually block specific URL's

what steps can I take to resolve the issue?

Thanks
