They make swimming sounds in actual water it doesn't make sense that they don't make sound when they're swimming in lava as well.

You can get sneak attacked by them because they don't make sound.
Update: I'm still experiencing the issue. I've tried re-uploading the world, seeing if that fixed it. It didn't. The issue is persistent and won't go away, the gamerule will even change while we are online.
Commandblocks are disabled, and there are no datapacks installed. No one else on the server is an operator, except for me.
I'm not sure it is, because the only gamerule I've changed is keepInventory: true.
I've encountered this issue in later versions. It's definitely a major bug that should be fix within the next few versions.
Ah that fixed it, thanks! But, I was thinking about the fact that some people use vanilla, and don't know how to use /gamerule and such.
