After Effects bug (I don't know how to say this, look at the picture)

Hello, I have a big problem with my Adobe After Effects.

I have some flats on my project, but one flat, is bugging on an other flat.

The "Shiomi Stadion" is the first flat. You can see, that this flat isn't on this point, but the flat will still displayed: http://i.imgur.com/4woW4rY.png

When I disable the flat, it will show too: http://i.imgur.com/qZiM9U5.png

And when I disable the "Stadionplan", the buggy "Shiomi Stadion" is no longer displayed: http://i.imgur.com/RAgsdeZ.png

I have restart After Effects, my Computer. I have delete all memory- and siskcache, few times. But the bug is still there.

Please help me, I don't now, how I bypass the bug.
