Skull of Undeath MTX for helmets doesn't count my kills

So currently this helmet shows 271 kills and 1 death.
But if I type /kills in chat it shows me 15 000 kills.
I've restarted a game, changed MTX back and forth, changed realm. Didn't help.

They aren't your kills, they are the minion's kills thus doesn't track for the helm. The /kill counter is non-discrete.

There's already been a handful of bug reports for this. I do not anticipate a change, but glad to be wrong as someone who plays mine builds.
