Unfortunately even CoD: AW suffers from some bugs and errors in its first week after launch. Which is comprehensible. But don't be afraid! New update is on the way. At least that is what SHG_Hammerman says at the blog.
– Prestige reset issues, including emblems and challenges.
– Adjustment to the in-game chat names notifications placement.
– Fix for weapon reloads counting as speed reloads in certain circumstances.
– Connectivity optimizations.
– Fix for stats accumulating towards leaderboards after prestiging.
– Adjustment to challenges to unlock Camos for weapons.
– Fix for round-based game modes, affecting Win/Loss ratios.
– Implemented ability to unlock eSports Rule options in Private Match.
