A common 1.16.x feature that god wrecked..
What it is? a Chat Packet.. cause by some plugin.
You can try ChatPacketFix Plugin [1.16.x] ChatPacketFix | SpigotMC - High Performance Minecraft

It will detect the message that is causing that and tell you what plugin is causing so you can remove or fix it

thanks ^^

i'll chceck it out
