"Agile Days Remaining in Sprint" and "Agile Sprint Health" gadgets don't auto-switch sprints (but "Agile Sprint Burndown" gadget does)

I'm using the "Agile Days Remaining in Sprint", "Agile Sprint Health", "Agile Sprint Burndown" widgets on my dashboard

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

But the "Agile Days Remaining in Sprint", "Agile Sprint Health" widgets aren't changing sprint automatically when one ends and another starts - I need to edit the dashboard and re-save the gadgets.

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.
