Worldspace water glitches

[Sixers2329]

I'm trying to make a world space and no matter what I do the water gets messed up. I've tried the exact same setup as the wasteland worldspace but as soon as I drag the land above the water's surface it breaks. I've tried making the default land higher than the water and vice versa but it breaks everytime. Sometimes if I load it in Fallout it'll be fine, but it's always messed up in the GECK. When it's messed up in geck its impossible to see what you're doing. You can only see the land when you look between the sky and the water edge.
