Sounds to me that you have those RSs listed in your unsteady flow file, but there aren’t enough flow records in each to cover the entire simulation.

When i faced this kind of problem,i changed the vertical discretization in the HTab parameter tab. By increasing the points, you cover a bigger area. For me that change, made the error disappear!
