Intersect Error

Hey guys.

when I try to intersect I do not get the intersection of marked area in the Picture. I have also tried to IntersectTwoSets but they are still not intersecting. I could creates these polygones by hand but then i must do 1200 by hand. I hope you guys have a solution for me.
