Hey, I don't know if 1.12.2 is still supported and I apologize if it's not anymore but I thought I'd report this since it's in the default generator that it comes with.
I noticed floating water was something that occurs on the cat generator especially if it's on a more flatter biome like the swampland. I also tested this without any other mods or anything that would modify the generation that could cause this. Maybe having the water be surrounded by gravel or sand could help a bit?
