beaches and stony shores not generating properly

sometimes beaches and stony shore biomes generate in really odd ways, they tend to generate in the middle of landscapes instead of generating near the oceans, this effects the gameplay and makes the new world generation feel so weird 

expected result : beaches and stony shores should generate near the ocean to make the transition between land and ocean better 

actual result : beaches and stony shores tend to generate in land instead of generating on the side of the oceans and they effect the new world generation in a bad way 

I hope this issue gets fixed before the full release of the new update
