grid tool problem in elevations

[Anonymous]

I am working in a Teamwork Project and we placed a grid tool system.
The grid fits corretcly to the inner edge of the wall.
If you generate an evelvation (section) than the tool jumps completely about 4 cm left or right. (in floor plans stays at the original place).
Is it a bug or is it possible to solve this Problem?

Thanks!
