Trees generating above a lake

So I just generated a new world, spawned on a beach and set off to collect wood. What i found was so messed up. I saw some trees spawned ABOVE a LAKE?!?!?! This is an issue here.

The number used to generate the world was 3362670731809701917 and the co-ordinates where the glitch is are x: -230, y: 70, z: 265.

Please fix this glitch soon as I prefer the world generated NORMALLY, if you dont mind. Hope I helped!
