EKReminder which was created by stock Reminder app has startDateComponents of nil value

It seems like reminders which were created from stock Reminder app, when fetched by eventStore.fetchReminder(), have their startDateComponents equal nil.
I have a few reminders as samples which were created in Reminder stock app, they clearly have start time.

But when I fetched and tried debugging, startDateComponents was shown nil

I'm not sure what I did wrong during fetching reminders... Because it seems to work perfectly with reminders added from 3rd party apps... Please help!
