Reminders with no time not showing in calendar panel

What I did:
Created Reminder in Reminders with no time associated with it.

What happened:
Reminder showed in Reminders, but not in calendar panel of Agenda.
(Reminders with times do show in Agenda)

What I expected:
To show in calendar panel of Agenda, before or after timed events and reminders.

Things that might be helpful to know (Agenda version, OS and model, etc):
9.3.1, MacOS 10.15.3

Did the reminder have a day associated? These should show up in the Agenda calendar panel. If it has neither a date nor a time it indeed won’t show.

Yes, definitely. When I add a time it appears in the Agenda calendar.
