"Agile Sprint Health" gadgets doesn't auto-switch sprints (but "Agile Sprint Burndown" gadget does)

I'm using the "Agile Sprint Health", and "Agile Sprint Burndown" widgets on my dashboard

All are set to Sprint = "Next Sprint Due (auto)".
Auto refresh is ticked on "Agile Sprint Health"
Refresh interval is set to every 15 minutes

But the "Agile Sprint Health" widget isn't changing sprint automatically when one ends and another starts - I need to edit the dashboard in System > System Dashboard and re-save the gadget.

The "Agile Sprint Burndown" gadget is behaving as expected - the dashboard showed the new active sprint without requiring interaction from me.

Attached screenshot of my config for reference.

Cloned from a similar issue (GHS-11955) which was set to be fixed in Agile 6.7.6 but we are on 6.7.7 and still unresolved.

Cheers
