MD 11 Planned order scheduling

Hi

When i create planned order with MD 11 and put basic end date as 11.03.2016  ( Today's date) and press scheduling  then  planned order is scheduled to  give basic start and production start dates in PAST(09.03.2016 ).

I dont have setting in OPU5 to allow start in past. Basic dates are adjusted to operation start date.

Please could you inform reason for start in past.
