weapons not properly unlocking

Hi @KotatehFox
To open an F2000 weapon:

1. You should get rank 10
2. .Second Assault Expansion must be obtained.
   
   
3. Get Assault Rifle Ribbon x1
    How to get him: Kill 6 enemies in one round with any Assault weapon.
   
   
4. Get 2x kill assist Ribbons in a round.
   How to get it: Hitting an enemy player and your teammate who kills him is a killing aid.
   Hit 5 enemies that equals 1x kill assist.
   You need to hit 10 enemies in a round with any weapon.
   
   
5. Kill 10 enemies inside the metro station in the vicinity of Flag B and Flag C.
   Flag A is outside the metro station.
   10 enemies must be killed in one round
   
   Not an arrangement requirement, you can start with any task

yep...did that, got the 10 kills etc, it didnt count, was hugging trains inside the metro B and c) said it counted at the end of the round but nope, ive done it several times, i usually dont leave the b area when i do this but it wont count it, ive done it multiple times

Hey, @KotatehFox   Do you own (Second Assault ) extension?

You must kill 10 enemies during one round, which means that if you kill 9 enemies and the round ends before killing the 10th enemy in the next round, you start from scratch

i have all dlc, and i killed 15+ on multiple occasions, ive met the requirements..inside the metro, 10 kills in a single match, was using an assault rifle to do it, i dont use pistols much and only one out of 15 was with a pistol so..theres no way i should not be getting this thing by now

so did it again today to see what happened

yes, how else would i level up and finish unlocking things? not exactly new to online games so..
