Windows 10: Not able to add trusted sites in windows 11

I am Using Windows 11. I have tried to add a website as trusted site through Control Panel/ Internet options/ Security / Trusted sites. This option is locked, and screenshot is provided here. It tells "some settings are managed by your system administrator". But I am the administrator. I have tried uninstalling antivirus, removing other accounts from system. please help me here.

Windows 10, Internet Explorer 11, Trusted Sites Greyed Out

I am using Windows 10, Internet Explorer 11, The button to add trusted sites is greyed out. Below that my custom button below is greyed out. This is my own personal laptop (I do not connected to any main office or main frame). How do I get this to work
again? I work in finance not computers so I need step by step help. I was able to add sites about a month ago so this is a new issue. I have seen something about GPO but This does not make since because I am not connected to a server and I am the only one
using my laptop.

 

Trusted Sites

I have an issue with one particular website that I use for work - I have to use internet explorer for this particular website and can't use Chrome. I am currently using Windows 8. This website has a certificate which is up-to-date and valid. I have added
the website to the trusted sites list and it saves it here. However, once I close internet explorer down and then re-open it and try to go back to this website I have to remove it from the trusted sites list and re-add it before it will run the certificate.

Any ideas? Driving me crazy. If I leave internet explorer open - but close that page down and re-open it, it works but if I have come out of internet explorer I have to re-add it to trusted sites.

Any help would be appreciated.
