Turtles Frozen

So I decided to breed turtles for the turtle master potion. After breeding them the pregnant  turtle just freezes. I tried all the solutions I could find. After none of them working I tried on a private world because I was trying to breed them on a realm. The same thing happened. Honestly I think they should just get the coding from the java version and tweak it a little so it works because when I tried on java it was fine.
