Fix integration tests

This MR fixes the integration tests. Since the test range was increased, it revealed several issues. Beside some smaller errors, it revealed some required fixes in the parameter propagation. These will be fixed within this MR. Furthermore it seems to show that the overstepping problem caused several errors in the tests. The overstepping itself is not fixed but will be shadowed such that the tests run through without any further errors. For that purpose the tilting of start and target surfaces is reduced.
