Are you sure about the phases are not other way around, ie Water being primary and air being secondary?

There can be several reasons for the floating point error. If your case is transient than try reducing the time step. A relatively bigger time-step can be the reason behind this error.

I hope you have fine mesh else that could also be another problem.
