Anti-Bufferbloat not working on upload speed

Hello.

I have a problem with the anti-bufferbloat. It does not limit the upload speed when I am playing a game even though it is working perfectly on limiting the download speed. I have searched for this problem and saw many posts regarding it and it was acknowledged as a bug and that it will be fixed with version 3.0. I have just updated to 3.0 and the problem still persists which sucks because anti-bufferbloat is basically the reason I bought the router. My cousin has the same router, ISP and download/upload speed as me and his is working completely fine. Any idea on how to fix this problem?

Thanks
