How can I set it only targeting the enemy but not my friend?
I have set it as mode all and the config file "Target Friend" = false
Is there a bug here?

Thanks

How is the person your friend?

So, it is working as intended. If you use the Friends plugin, it works, however it doesn't work with teams.

I updated the plugin to support teams, assuming this is what you meant.
