Xbox Vet Achievement bugged?

[paper heart]

I can't get the achievement for 100 koth wins and I know I have far more then that. I'm over 80 hours in, and have been consistently getting 12+ wins a day for more than a week. Match that with all my wins before I got to #1 rank and I know I have more than 100 wins, easily. I've played a mix of normal and mutagen mode. Would mutagen not count?

I guess I'm just looking for an answer as to whether it's bugged or not, officially. The unlock rate has remained at 0.01% from the day I started playing until now. I just want to know what's going on...

I unlocked this achievement by doing easy runs, having 5 or 6 koth wins at the end of each runs. I counted them on paper so I knew where I was, and it unlocked at 100, no more no less. I don't know if mutagen mode counts or not =/
(Normal mode does count, I did one to unlock koth mode, but it's bugged atm on game pass so I went on easy mode -and if you play on xbox, you can enjoy easy mode to count since it is not supposed to count on the next update I think)

My buddy has 108 wins, 103 being normal and his isn't unlocking either. He actually kept count. I didn't feel the need to keep track because I'm far above 100. My 10 wins did unlock through easy, so I assumed the game counts it properly and would unlock at 100 as well. Maybe easy wins are the only ones that count, haha.

I'm on gamepass, if it's bugged there, shouldn't it be bugged wether or not I actually own the game? It should be the exact same version either way I thought.

Update: I've bought the full deluxe game. No achievement unlocked from normal or mutagen mode after their respective wins. I guess all I have left is to grind easy mode and keep track.

I wouldn't be so determined normally, but they lock a 51 point achievement behind 100 koth wins. I REFUSE to have my gamerscore not be divisible by 5!
