XP Boost Bug

I would like to report an issue regarding XP boost. When I activate 'Career' XP boost and then activate 'Hardware' XP boost at the same time, the 'Hardware' one gets deleted and doesn't show timer on it anymore. And after the match, I also notice I was getting normal XP for my weapons. So it is not a visual bug with the timer, but the XP boost gets deleted.

I have lost countless amount of 'Hardware' boost because of this bug. What I'm doing now is to activate either one separately until this issue get fixed, which is inconvenient and time wasting.

Thank you.
