Check the depth/height specification. I think it's linked to the mesh position, so whilst the height is 2.3m (you're possibly correct) based on the numbers given I don't know the mesh coordinates. 

Check the mesh resolution around the top of the unit and free surface, you may find it'll break the surface and needs a higher cell count in that region.
