Execution archive doesn't work

I had 4/8 at the start of the match and tombsonted three survivors with Myers, which is how I got the previous 4 (despite actually only tombstomed just three and sacrificing the last one)

Next match I sacrificed all four as Spirit and got 8/8. It seems to only count 4Ks regardless of if you actually kill the survivors.

The description just says to kill 8 by any means
