Dog tags not brought to dog tags list

i've played the game: http://battlelog.battlefield.com/bf3/battlereport/show/1/[edit: credit card info removed]7/

and took dog tag of http://battlelog.battlefield.com/bf3/soldier/apocalipse94/dogtags/294807786/pc/

but my list of dog tags still not mentioning it even once [the last of this roar is before 4 months].

i could understand if taking it more than once from the same person is counted only once, but none?

it could be connected, to the fact i left the game before the end of the round -> then it should be a bug

interestendly, the dude with this roar dog tag, have my dog tag listed, and he also left before the end of the round
