This happened to me some time ago. Some predefined video configurations from game setup utility, let you set higher configurations that others. For example, if you chosse the video configuration as "default", depending of your graphics card, you be able to set some values of water, but no all. Try change the predefined video configurations just you found one that let you set higest water (no always maximun). In my case, it was nvidia 6800 settings.
