Battle Royale Challenge isn't Properly Tracking

Underneath "Challenges", in the section titled "Assignments", there's a section of them called "Initiation".

In that section, there assignment called "Battle Royale Challenge" does not properly progress at the final stage.

The final stage says to "Reach maximum training level in Battle Royale" yet whenever I reach it in the BR mode, the challenge does not track. Because of this, you are unable to get the weapon camo at the end of the assignment.

Furthermore, there seems to have been an update that changed the second section of the challenge where one of the challenges is to "Acquire a tank in BR". This challenge also does not track properly as in multiple matches I have gotten either the tank (MBV) or the armored carrier (IFV)  and it seems to track randomly.  I only bring this up cause the game might not track the final part if the parts before are not fully cleared and also to bring this up as this might cause other people who pick up the game later to not bring progress.
