Find WaterFilter BUG

hello everybody !

Today I met when using WaterFilter save an interesting question , The Radius, WaterHeight, Center, ShapeType cannot be saved

WaterFilter.java in public void read(JmeImporter im) public void write(JmeExporter ex) There is no Radius, WaterHeight, Center, ShapeType

I don’t know what is the situation, it is engine violations maintainer is missing, or deliberately not to write !
