Local Server Multiplayer people who join have fishing rods not even attached to string

When I started up a world with my friends we decided to go fishing when I tried to fish everything was fine. But when they tree to to the string wasn't even attached to it and it just looked like the bobber was in there. It worked fine for me, I'm guessing it was because I was the host. But when I looked at his fishing rod on my screen it looked perfectly fine. But, on his screen minr looked fine because I was the host but his looked messed up. He could still catch fish but the fishing rod glitch in really messed up our fishing experience. This bugs happens in survival and creative.
