LiquidBounce Skinderp error?

Hello dear Minecraft community. At that time I hacked myself, but stopped at some point because it was no longer fun. Today I saw a player with a pretty cool Skinderp on the server Griefergames.net. I then started my Liquidbounce client to present mine. After I deactivated it again and switched back to my lab mode, the headphones, hoods are gone. I have already uninstalled and reinstalled the Minecraft launcher, uninstalled the Liquidbounce client and changed my skin, but it still does not work. Can somebody help me?

Here you can see how headphones are gone.
