Scorpion Commendation

i have noticed today my commendation for Scorpion tank kills is stuck on 1/3, i have gotten about 3 on big team today, its definatly said ‘Destroyed Vehicle’
this is in matchmaking, big team battle, its just stuck at 1/3, so i’ll never get to max them? can anyone from 343i maybe ressolve this for me?

I have gotten around 60+ scorpions destroyed and It has only recorded 9 overall. 343 needs to fix it because I’m tired of it not giving me my commedations.
