KK equity question
Preflop: Hero is SB with KK
2 folds, CO raises to $4, BTN raises to $33.35 and is all-in, Hero calls $32.35, BB folds, CO raises to $121.40, Hero raises to $209.45, CO calls $57.22 and is all-in
CO shows QQ
BTN shows QQ
Flop: ($392.59) 54A (3 players, 2 are all-in)
Turn: ($392.59) 6 (3 players, 2 are all-in)
River: ($392.59) A (3 players, 2 are all-in)
So something seems wrong with this hand. I am 96.3% favourite to win, but this is from HM2:

It says that EV diff. is -$56.08 ?

Someone knows why is it like that?
