iOS - Multiple App notifications after calendar event update

Hello

When I update an event, the NC app generate 2 notifications

  1. First one to inform that ā€œxā€ has been updated/deleted to ā€œxā€
  2. Seconde one to inform that the event ā€œxā€ has been updated/deleted to the calendar ā€œxā€

Is it normal, Iā€™m the only one?

Thanks.
Seb
