[iOS 17DB3] Can’t create custom focus Home Screen (Resolved - User Error!)

I don’t seem to be able to customise the Home Screen layout for a specific focus mode. Whenever I change the layout of a specific focus mode, it changes the home screen across all modes.

I am entering the mode from the Lock screen, unlocking, and putting the home screen into edit mode. After making the changes I am locking the phone and reverting back to the default focus mode.

Am I holding this wrong or has this broken in 17DB3?

Edit: Resolved thanks to @dnzm@lemmy.ml
