Battle Royal Challange 5 Initiation

Battle Royal Challange 5 Initiation is this a bug or am i stupid

is the Maximum Trainings level unreachable ? because the training path/level is infinite evan if you reach the "max" level 4 ten times it does not count, and if the trainings path means somthing else its very misleading , i tryed a lot of stuff 

the trainings mode and nearly everthing there (level 4 done uo to 10 times in one game)

the normal mode in quads and dous and the level 4 up to 10 times in one game

2 wins in all  modes 

doing the other quest (battel royal challenges)(privat and speceslist)

and a lot of small other things like all missions in one game looted up to 30 boxes in a game got over 10000xp with all classes 15 kills + etc 

so long its not reach the 20 kills badge twice. i did basclly everthing else and i dont get it :( would really love that to be fixed that i can get the 100% done...

or is it somthing else ?
