2D "Z-Index" Overlapping Problem

Hi there!

I have a problem with overlapping sprites in “Playmode”.

The big picture is the 3d-Level-View. the camea looks from right to left.
But in the Playmode the fence-sprite is shown above the other sprite.
Whats the problem?

y-coordinates of the fence is -100 the others 0.
