I’m trying to add an event to my calendar but after going through all screens, it starts right away anyways.

Cause

The event does appear in your calendar, just not on the day you picked but randomly at some other date. Sometimes a date in the past is picked, triggering the event right away.

Solution

Currently none but only old saves see affected by this. New saves seem fine.
