calendar issue

[kristin]

I have a number of multi day events in my calendar. Most of them are purple. I change the colour to red once they've been completed so I know they're done. In the last 2 weeks, every time I change the colour it creates a new event for that day rather than just changing the colour, and the purple one stays in my calendar.
Is there a way to stop that from happening? I just want the colour to change, for the event to stay in my calendar, and not create a new event for that day.
I have a Samsung note 8, and just updated to Android 8.0.0 a few weeks ago

That doesn't happen for me as I just tried it.
The only thing I can suggest is see if your calender is up to date. Worst case scenario is that you delete and re-download the calender app

it's the samsung calendar. I dont see an option to delete and re download...

[kristin]

this is what I'm seeing. normal event with purple label, change it to red, click only this event, then there's two events...

Yes your right you can't delete but when you go into settings... calendar... 3 dots top right ....
uninstall update then update again...

Hey @kristin, please try deleting and re-downloading the app as Echo has suggested. If your are still encountering the issue after that please submit an error report.
