Halo 4 - BR Commendation Question

So i’m trying to master the BR but Waypoint says I only killed 221 players with it instead of the 1350 i killed total with the BR? How does this system work? Im confused

You’re probably on the last level and its says 221/1000.

NVM PLEASE LOCK!

Yeah Each Weapon level Restarts the Kills in all Weapon
Commendations, that’s not Your total kills.
