Broken Structures

This world with the Caves and Cliffs switch on? If yes, was it there before without the switch on (ie you turned it on, and did not create the world right away with "Caves and Cliffs")?

Seems to me that biome blending tore the structures apart and attempted to blend them into the terrian.

This is happening on multiple platforms. I have experienced this on iOS. Village structures were blended along chunk borders with new terrain. I upgraded my latest 1.17 world to 1.18.2.

Screenshots of village structures being blended along new chunks.

Minecraft Bedrock PS5 v.1.19.40, only 2 or no elder guardians in ocean monuments and no sponges in Survival mode. Guardians are outside in the ocean still.  I confused why this is a "Broken structure" bug? MCPE-144292 describes the issue.
