On both my iPhone 7 & Macbook Pro (2017), whenever I set a reminder, it automatically adds a "due" column and changes the notification time. I just set a reminder to be notified at 9:30 am tomorrow, and it has automatically changed it to 23:20 tonight. I've turned the "remind me on a day" button many times and manually changed the due date & time to correspond with my initial intention but it continues to change automatically. How do I turn it off and be reminded when I want to be reminded? Thanks.
