Animals are stuck at one place and keep vibrating and block the whole row in front and back and sideways.

Some Animals are stuck at one place they can't move. They keep vibrating at one place as if they are lagging. I can't even kill them. If I shoot it with arrow they arrow is stuck in the air above them like one block in air. They block whole way in their row above,behind and sideways. I dont know the exact distance of blocks in their row what they are blocking but it is like mome than 50 i guess. Onl thing I got to do is reload the game again. But at some point they still spawn somewhere else. Please fix it. I have device xaomi redmi note 5.
