Parrot Bugs

In my survival world, I have parrots that I have set to sit at my base before I leave the world. Once I go back to the world, the parrots are there as I left them, but they are not sitting. This has been going on since I got them. Also, I left my world with parrots on both shoulders and when I got back, they begin suffocating in the ground below me. It was sad to see These "bugs" are annoying and should be fixed.
