How to make it PVE

I am writing you because I try everything to have the bubble PVE so players inside can't shoot and kill people outside.

Wen I am able to make it PVE, there only Nightmares and easy that spawn nothing else. 

Can you tell me in the code where I can change so all is PVE and all level spawn?

 

Thank you . 

hi, please show me everything the plugin says when it loads.

Convert PVP to PVE will make them all PVE. config
