Opening an anvil shows many false key resolutions

Open any paperMC server and try.

Hi thanks for opening an issue @zyrafaq.
Unfortunately I wasn't able to replicate this at all on my own Paper testing server.

1. Are you using the current latest release version?
2. Do you have debug alerts enabled? (Debug alerts would show verbose detection alert)
3. Do you have other similar protection mods installed? (Would be nice to know all your installed mod list or console logs)
4. What version of Minecraft are you using?

Hello, I am using Minecraft version 1.21.11 (with prism launcher), I don't use any similar mods. No, I don't have debug alerts. Also I am using OpSec 1.1.0

I am aware this is not the super latest version, though it shouldn't matter.

In the anvil, try enchanting already existed items with books.

Didn't occur in my testing:

I think it only happens on some servers
