Points from kills won't track for some of the camos

I was grinding for a camo on the Strv 103-0 and checked before hand that both camos where on the same counter which they were. I played and got the winter camo all finished and thought the score for the next camo would be at 520. It didn’t budge from the time I started grinding for the camo and stayed at 483 points instead of being at 520.

I tried to play a game to see if it would climb but it hasn’t even moved from 483 points.
