XP does not register as usual after matches

Had a couple of games where it was quite hard to do the DMR headshot challenge so i decided to try my luck in the casual breakthrough...not much luck there either as i was being targeted for lack of silencer so i decided to just go for the points. At the end of the match i noticed that i got far less xp than i usually get from a breakthrough game and thought it was only because of the casual gamemode so i hopped into the normal multiplayer mode.

First game had 4000 something score and only recived 2000 xp from it.  I thought something is bugged so i restarted the game and hopped back in conquest. First game, same result, i got faaaaar less xp than the double xp event has been rewarding so i went back to breakthrough hoping it would cancel whatever happened in casual breakthrough but it did not. Was third on my team with 6365 score and only received 2730xp with the accolades, bfpro boost and double xp (check attached screenshots). During the day a game with that score would yield around 30-40k xp.

Has something happened to my account or is the xp limited after a time?

If the latter please do make a note and put it in the game so every one knows their xp will be limited after a while, if not could you please undo whatever happened or patch it if it is a bigger issue 

Thank you
