When my friend gave me his Minecraft world, when I went to go and play it I noticed that I could no longer tell my cats to sit down or walk around but could still feed them. What was even funnier is that while I couldn't interact with my cats, I could interact with my friend's dog and could tell them to sit or walk. Punching them would make them stand up but I'm unable to actually get them to listen to me and the only way they'll sit down is if they go onto a chest. Even more odd is that this problem never occurred when he was hosting the server and it was only until I had downloaded the world and played it, it had happened to me. I really hope you'll be able to find a fix to this so thank you for taking the time and reading my complaint.
