Caves and Cliffs: Experimental Bedrock 1.17 (Bug); all caves are completely watered to the surface.

All caves are completely watered to the surface. Unable to Explorer and mine. Since update 1.17, I have enabled the experimental 'caves and cliffs' mode, since then I've been playing and all the caves below ground are completely filled with water. I used other 'seeds' and in them the problem remains. I found the new biome "Azaléa" in a seed in layer 32, and it is filled with water, being unable to explore. Not only in this seed, but in all I've played so far. Bedrock Edition PS4.
