Reminders App (Mac and Iphone) - Natural language input in german

This is a bug which is driving me nuts for months now and keeping me away from using the reminders app.

When using the reminders you can use the natural language input (Tomorrow, 21 jan) then you get a suggestion and when you click it on the mac (or tap it on the iphone) the reminder-date is set and the original text disappears from the input field.

example: 21 jan *tap* Getting bread creates a reminder "Getting bread" on january the 21st

If you (like me) use the OS in german, there are suggestions, too, but they aren't removed from the reminder itself.

So, if you type "21. Januar" *tap* Getting bread creates a reminder "21. Januar Getting bread"

Any idea, what I can do here?
