Mapped Boundary Condition

I have used the 'mapped' boundary condition for a channel flow with simpleFoam. It worked fine and gave me a fully turbulent velocity profile. However, when I applied it to an asymmetric diffuser case, the profile was inclined, meaning that the velocity is higher on one side of the inlet channel than the other. And also the solution is a mess.
I have set it by following exactly the tutorial case incompressible/pisoFoam/les/pitzDailyMapped. I even rearranged the vertices for the 'mapped' patch such that it goes in the same direction as in the tutorial case.
I switched back to 'fixedValue' and the solution became normal.
Was there anything I did wrong that screws up the solution? Any hint is welcome.
