[Evolution] No Tasks in Calendar view

(Linux Mint 20, Evolution 3.38.1 via Flatpak)

Not sure what's changed, but for some odd reason my tasks are not
showing up in the Calendar view. In Tasks/Email views, all of my tasks
are shown as normal.

Is there a way to reset the Calendar view? Initially, when I first
reinstalled Evolution last month, it would take 30-60 seconds for my
Outlook account to refresh and the tasks would show up again. But that
has also stopped working.
