Default Two-phase-liquid film-VOF

I have some starting problems using the VOF model in Fluent 6.2.16. The case is a 2D two-phase diffuser flow. The liquid film will be modeled with the VOF model and the dispersed phase will be modeled with the Euler-Lagrange approach. My problem is related to defining Boundary Conditions for the individual phase. There are two inlet boundaries, one small close to the wall for the film flow and a second in the middle for the air flow. As I choose Define..Boundary Conditions I am able to choose a phase for a Zone. I define the first phase for the specified inlet zone. As I choose the second phase for the other inlet zone, the first one changes. Is someone capable to help me?
