Problem with Bonus xp

since i'm back playing blackshot (a month ago)  i noticed a problem with my account ! only the original xp adds to my account but the bonus xp don't ! i kept track and i did the math ! and i'm sure it don't add up ! it's like i'm not getting any bonus xp ! which is so bad because sometimes i get 1000+ bonus xp per game. i asked other players if they have the same problem as me but they don't ! a message to the GM's , if there is a problem please try looking at it and fix it ! thank you in advance ! 

my in game name is charara.
