Random leaf blocks in the air

Recently ever since the small caves and cliffs update that added lush caves, there have been random floating spruce leaf blocks in the air surrounding my base area. Some things to note are: •this is on a bedrock (Xbox) creative mode multiplayer world with the caves and cliffs setting switched on and no other experimental features •These leaf blocks are in strips anywhere from 3-5 blocks long and sometimes have multiple layers stacked •They cannot be removed, myself and my friend have tried breaking them and burning them but they just regenerate within a few minutes •they are spruce leaves and they spawn in biomes spruce trees don't typically generate in (Dark oak forest, ocean, river, and plains) •it started out with just 3 rows in random spots and throughout the last few weeks of playing they have started generating in more areas. Additionally a similar thing happened in my siblings world where a 1 (one) block thick 30 block long river biome with a tree spawned in and was not able to be removed
