Training paths incorrectly awarded experience early in the match

Simply said, training path experience is carrying over from previous matches or is being added incorrectly somehow.  I've been killed by recons with confirmed kill in the first couple of minutes of gameplay, with the highest player on the team (not the shooter) having around 2000 score.

I've had this happen to me a few times but I've been on the receiving end of it many times.  It is most recognizable with recon confirmed kill, but I've seen other "6 key" abilities such as the assault one being used impossibly early on.

Thank you for reading and please upvote if this has happened to you as well.
