Weird ScreenTime notifications and random listing in App Limits

[sixc]

I was getting weird ScreenTime notifications. Then I found "montgomerycountymd.gov" in my App Limits settings. Problem is I NEVER even visited this site on any of my devices let alone adding it to App Limits. Is this just a bug or should I be worried about device security? I ran a Malwarebytes security check and the results indicated that my system is free of any malware or malicious treat. Has anyone faced similar issue?
