Block Entities drop from ground and walls randomly

Block Entites drop from randomly from the ground and walls. It seems to only happen on Oak Wood and Stone. Also when ever I walk around 40 blocks away, some signs fall off when I come back.

Block Entites that drop: Torches, Signs, Item Frames, Ladders, and Paintings.
