Sceen Time shows a Family Members Phone, Not Mine.

If i go Settings > Screen Time, the phone that's displayed first is my Son's phone. This has been an issue for my iPhone 7, X and now my 12 pro. I can only assume that its a bug thats following me across backup restores.

I can disable screen time on all the families devices and then re-enable it just for mine and it still stubbornly shows "Josh's iPhone" with "as this device is used screen time will be shown here"- this is always blank regardless of whether or not i enable Josh's phone for screen time in place of it being mine (Dean's iPhone).

When i'm re-enabling screen time, i'm obviously selecting "this is my iphone" from the list of options and im correctly the person signed into my phone with the correct apple account as the account owner and parent.

Peculiarly, the screen widget for screen time DOES show my phone and its associated screen time.

Any ideas on how to resolve this annoying issue?
