I don't know if this is just me or if many people have experienced the same thing, but when the calendar integration is turned on, events are automatically added to the calendar when you open the app, which I think is very convenient, but naturally this time period changes depending on your sleep score, so there is a difference between the events that were displayed yesterday and the new events added today, but because the previous events have not been deleted, there are duplicate events.

I think this may be due to a technical aspect of Google Calendar, but what do you think?
