Fantastical accepted event alert

Summary: When I accept an invitation the accepted event does not have an alert

Steps to reproduce:
- Open Fantastical iOS
- Tap the plus icon
- Type "Test 10am"
- Tap "Add"
- Tap the "Test" event
- Tap "Edit"
- Tap "Invitees"
- Type the name of a friend
- Tap "Done"
- Open Fantastical iOS on your friend's iPhone
- Accept the event invite
- Tap the accepted event
- Notice how "Alert" is set to "None"

Fantastical iOS Settings:
- Default Alerts are set to "1 minute before" and "15 minutes before"

- Notifications are enabled

Is there a way to get invitations to respect default alert settings?
