Hi, and welcome to the Apple (user-to-user) Community.
Re: "I see "Privacy" when I click on the Control Center. How do I fix this?"
Wondering if Apple Support's online article (link below) may be helpful, (seems it does not yet include Sonoma.)
Use reference modes with your Apple display - Apple Support
Eg: says:
"You can choose which reference modes appear in the Display section of Control Center:
Choose Apple menu > System Settings (or System Preferences).
✽ Click Displays.
If you have multiple displays connected:
In macOS Ventura, select the display at the top of the Displays window.
In macOS Monterey or earlier, click Display Settings, then select the display in the sidebar.
✽ Click the Preset pop-up menu, then choose Customize Presets.
✽ In the Show in Menu column, select the reference modes that you want to appear in Control Center,
✽ then click Done."
All the best :-)
