Is the magnitude of the displacement the same when you use a linear material?  If so, that would help isolate the issue.  The displacements are in the opposite direction because the initial strain in the second model is zero so the bending stresses of the initial stress deflect it upward.  In a 1d case if you pulled on a spring and then applied the resulting tension in a new analysis it would contract the spring.
