Xp drops wrong from my enderman

so i just got paper, to use pluggins to get skins on offline mode, and the enderman in my world dont give xp anymore, in vanila server is ok, but in paper it does not work, im fairly new to this, so please help

We don’t support offline mode without bungee with online mode, just tested too and they drop the correct amount.

the xp was “compressed” it only showed fewer particles, but thanks!
