Date Due Date is different formated

I have the problem, that the “date due” is not correct formated. It appears in the subpannels history and activities under the contact. The first line with a “date due” is formated like the users preferences. All the other lines are raw like in the database.
Any idea

Could you post a screenshot showing this

I posted some Screenshots. Do you have any idea?
