Hello fitch29,
Is this happening with a specific Focus? If so, test another Focus to see if it persists.
If needed to resolve this, you can also delete the Focus and recreate it using these steps: Set up a Focus on Mac - Apple Support
Add or remove a Focus
1. On your Mac, choose Apple menu
> System Settings, then click Focus
in the sidebar. (You may need to scroll down.)
2. Do any of the following on the right:
- Add a provided Focus: Click Add Focus, then click a Focus, such as Gaming or Work.
- Create a custom Focus: Click Add Focus, then click Custom. Enter a name, select a color and icon, then click OK. For example, you might create a Study Focus. You can create up to ten.
- Change a custom Focus: Click a custom Focus in the list. Click the icon to change the name, color, or icon of the Focus.
- Remove a Focus: Click a Focus in the list, then click Delete Focus at the bottom of the window.
A custom Focus is deleted. A provided Focus, such as Reading or Mindfulness, is removed from the list but is still available to add again later.
If you keep Focus up to date across your Apple devices, the changes you make on your Mac are reflected on your other devices.
Keep in mind, that if you have 'Shared across devices' enabled it will sync your Focus status across your other Apple devices.
Let us know if that helps out, take care.
