Class Challenge Progression

There seems to be a TON and i mean a TON of issues regarding the class challenges progressing. It took way too long to complete the 100 smoke assists on support since some revives and kills weren't counting half the time. Buddy says his engineer isn't progressing the vehicle healing. Now im doing the intercept projectiles with the GIS and NONE of them are counting on various modes. Its so butt to because its taking forever as it is but its also not progressing.
