What I did: I linked a note to a calendar event.
What happened: When I checked my calendar app (Apple Calendar), the URL of the linked note was placed to other events. This happened to other events as well. BTW, I have different calendars on my ical.
What I expected: The note I linked would match the event.
Things that might be helpful to know (Agenda version, OS and model, etc): Agenda version 1.1, MacOS High Sierra 10.13.3
