Rain goes through blocks after disabling ripples

[ManHatos]

Rain in the pack is supposed to get blocked by blocks, however after I modified the shaders I noticed that rain gets through blocks.
My only modification was to disable ripples:
Shader > glsl > natural-mystic-config.h :

/* Define to enable water ripple animation that appears on the ground when
it's raining. */
define ENABLE_RIPPLES 1

Modified to:

/* Define to enable water ripple animation that appears on the ground when
it's raining. /
/ #undef ENABLE_RIPPLES 1 */
