daylight simple water projector issue

(using the free version of unity3d) So i made a daylight simple water object, placed it on the terrain and added a projector to it. everything worked fine until i added another daylight simple water object with a 180 rotation (to make it look like you are underwater when you fall through the water and look up) at this point when i played the game the projector started acting horribly buggy like so: https://dl.dropboxusercontent.com/u/51163820/Glitch.jpg (only imagine its constantly changing when i rotate the camera.

What could be causing this?
