I am trying to create a Pixelmon server for me and my friends, but LuckPerms isn't being recognized as a mod when the server is launching. I have tried different versions but all of them do the same thing.

[Server thread/INFO] [FML]: FML has found a non-mod file LuckPerms-Sponge-5.0.70.jar in your mods directory. It will now be injected into your classpath. This could severe stability issues, it should be removed if possible.

Somehow overlooked I didn't put the spongeforge in the mods folder.
