What I did:
I create a reminder using the \remind function in Agenda. The little clock item appears and all looks good - this is on MacOS
When checking the Reminders app, I see that there are two identical entries, each with the same callback URL.
What I expected:
Only one entry in the reminders list
Things that might be helpful to know (Agenda version, OS and model, etc):
Agenda 14.1.1 on MacOS 12.4
