The problem with Kursplan. (Farming Simulator 15)

The problem on the map Warsaw. 14 field planted with grass, after the grass grew I wanted to mow the grass. Chose a tractor with a mower, clicked on Different field of work -> route Generation" and when they want to choose the right field, Kursela sees 14 fields. What could it be? I remember playing on a different save game, and everything worked perfectly. I would be grateful for answers. Version Colsplay the latest.
