Water4Simple & Water4Advanced internal LOD issue

This is a flat terrain, and above (0,2,0) a Water4Simple is placed.

There appears to be an internal LOD that I can’t change, where the effect of “light bending” stops after a certain distance. It is best shown through a picture:

Here is the picture.

Best noticed if you zoom in completely: https://i.imgur.com/RaFp9cw.jpg

The effect is same on two different computers (one laptop, one desktop with different GFX).

Does anyone know how I can extend this effect to be applied across a larger distance?

P.S. this is not where the water object ends, here’s a different shot: https://i.imgur.com/GlM673g.jpg

(partial fix) when “Edge Blend” is unchecked, this problem disappears, although some Water4 functionality is lost. This is true for both Water4Simple and Water4Advanced.
