[Bug] Radios break after rejoin

[RedstoneGyerek]

Describe the bug
Radios (Transcievers and Spuddies) no longer work as intended after rejoining a server. When I join back in, the radios are fixed to the position I left and joined at. Meaning, when someone talks in the radio, i hear the sound coming from that exact location.

To Reproduce
Steps to reproduce the behavior:

1. Join server
2. Set up a radio channel with someone
3. Leave server
4. Join back in
5. Enjoy the bug

Expected behavior
The radios should keep the sound attached to the user.

Version and Mod Loader:

• Minecraft Version: 1.21.1
• Simple Radio Version: 4.5.7.9
• Mod Loader: NeoForge

Additional context
We're using Sound Physics Perfected by RedLifedev. Maybe it's causing issues?

Another discovery, when the other player walked near me, my radio was magically cured and the sound reattached to me.

And another, when I drop my radio and pick it back up it also starts working.

I am having the same issues on 1.21.1 NeoForge. I am not using any sound physics mod, so it doesn't seem to be caused by that.
