I'm having the same problem again.  Other images I have done with water planes have work fine and I don't see that I did anything deferently.  I deleted the ground plane and loaded the water plane (top button on the left hand menu).  As before I cannot access the water editor controls. Use Global Wave Control is greyed out and will not allow me to uncheck it.  When I go to the Sea layer in the layer menu cut is not available so I cannot delete the sea and reload. I am using a metawater material. I have tried saving the scene and reopening it and  that did no good. Any other ideas?

BTW, I am using latest build of Vue 8 Esprit with Ecosystem module added.
