Automatic reminder on Calendar's events
Hello,
Yesterday I added many events on my Mac's calendar, which is synchronised with my iPhone. I didn't put reminder on any of events, but after sending them to iCloud and then to iPhone, all of them have a reminder set to "at the time of event". What to do? I don't want whose reminders, they are in all of my calendars, on Mac they're not showing, only on iPhone.
Thanks.
iPhone 8, iOS 12
