same issue here, running paper 1.20.6-112-master@347bbe3 with these plugins: BetterTeams, GrimAC, ProtocolLib, PvPManager, voicechat

Guys, please help with my issue! It's been 4 days! It's called "holograms messed up", and it's caused by ProtocolLib

like @EuSouVoce already mentioned: you are not using latest build... 679 is NOT the latest dev build! (it's 689 for now)
And this was already mentioned here #2944 and here #2938

And @KenterWasTaken : please stay on topic.. you've already opened an issue... this issue here has nothing to do with yours...

@Jeppa yea, but no one is answering my issue while I made it way before this one for example, yet it did r get a single reply!

@KenterWasTaken free software does not provide support guarantees.

@Janmm14 this is long since fixed btw
