Administrator account

Windows 11 Pro
The lines under my user name show Local Account and, on the line below it, Administrator. However, my account doesn’t function as an administrator.
Settings, Accounts, Family: No user names whatsoever appear, not mine and not the hidden Administrator account which I enabled.
I tried changing my account type with Command Prompt and with PowerShell. In both cases, a message was displayed that the account is already a member of the group.
I changed my account to standard, in User Accounts and then switched to the Administrator account to change my account to Administrator. But I found myself right back where I started. Local Account and Administrator.
