I need help. Damage DayZ

[jdm]

Hello everyone, lately I started to play mta and some friends gave me an idea to create a mta dayz server. And as I am not aware of "script", I see tutorials on how to create and lately I am about to open the server.
But I discovered a bug in DayZ game mode, added new weapons and found that it is not causing damage to all weapons;
I need your help, I just need to solve this "bug" to leave the server online.
Thank you all for your attention. If you can help me, I'll be grateful!
A big hug.
I'll leave some prints of my problem here
