iMessage debug system-id all zeros, followed by mac address?

[Swerve]

I ran imessage debug, and noticed my system-id had all zeros, followed by my mac address; the rom had my mac address as well. I haven't activated anything yet (imessage, icloud, itunes). Should I generate a new one? I read that it's some kind of Gigabyte bug. Also, the BoardSerial number (MLB?) doesn't match with the first 2 letters serial number. I tried using Ares from Pandora tool to generate a new one, and it said it's the same as  Board Serial Number;

 

So I'm pretty confused right now. Generate system-id, leave Rom value as mac address, leave or generate a new MLB?
