Log Spam [Server thread/ERROR] [mcjtylib/]: The mob spawn amounts list for mob minecraft:axolotl is missing!

[GnomoMuitoLoco]

I'm having this problem with a player's chunk being spammed, how can I fix it? I've already tried updating all the mods that use mcjtylib-1.20-8.0.6 to the latest version
My server is 1.20.1
