Cookie whitelist settings

In the Cookies and other site data section of privacy and security settings I am unable to delete websites from " Sites that can always use cookies"

When I click the trash can icon, nothing happens.

I honestly don’t remember granting access to the majority of these sites as well. Maybe I messed up/forgot, but it seems like some websites are able to add themselves to the list

V1.18.75, macOS Catalina 10.15.7

Still an issue. In the past 3 days, a couple more sites have added themselves to the white list. I’m positive I did not put shields down for these sites. Now I can’t remove them either.
