Adding a second water component in the same level break things up

I don’t know if it’s something basic that I’m doing wrong o I missed from the documentation, but I have had so many problems with this plugin that my brain refuses to keep debugging it.

This is my level with a water body ocean

And this is what happens after adding a water body lake

Why is it doing that?

Bump! Unticking “Affects the landscape” makes the water stop rendering.
