Centrifugal pump performance analyzing

Can anyone explain the solution for solving below mentioned problem...

I am using ANSYS14.5 CFX to analyze centrifugal pump performance. The impeller (Rotor)and casing (Stator) are designed as the fluid domain model and saved in IGES format. WHen it imported in CFX tool , it automatically created the interfaces between these parts.
The interface option is chosen as FROZEN ROTOR and it pitch angle option is chosen as AUTOMATIC. At the time , the error is shown.

The error message:
The interface , the pitch angle ratio(1.09) is not same as the area ratio(4.62)

Have you checked the Rotation axis?

By Facing each other at the Surfaces of the Rotor and Stator the problem will solve.
