Hello,
Sometime corrupted User Profile will causes this kind of issues. I suggest you to add another Microsoft account by following the steps mentioned below and try to change the setting from that account to see if it takes changes.
* Click Start,
* Navigate to Settings/>Accounts/>Your Account/> Family & other users.
* On the right pane click Add someone else to this PC
under Other users.
* If you have another Microsoft account try to use that or else follow the steps to sign-up for new and switch with new Microsoft account.
* Sign-out from the old and Login with new Microsoft account.
Once you're sign-in with new User Profile, then please work around and check if it helps you.
Keep us posted the outcome.
