You are logging in as a regular admin and not the keymaster.

Only keymasters can see the advanced plugins and settings.

Did you demote yourself from keymaster to regular administrator?

Or are you logging in as another user you created as an administrator?

If you are user # 1 and still don’t know what is wrong

you can try using this plugin to fix your access level
