Jungle Blocks, Leaves, Vines, and Water Source Blocks Spawning Randomly

I play Pocket Edition Minecraft, and ever since the newest update on October 14th, 1.17.40, me and my friends have noticed floating blocks of Jungle Wood Blocks/Leaves, Vines, and Water Source blocks appearing in thin air. As far as I can tell, they are continuously spawning all over the realm, all over every biome. I have provided screenshots in hopes that they help at all.
