Battle Royale Challenge 5 “maximum training level” is not tracking progress.

Hello, Making the issue known to users . Currently many people are unable to complete this challenge due to tracking progress of training level in Battle Royale . My personal experience I’ve tried to complete this challenge for about 2 days maxing out training level multiple times . Level 4 progress sometimes resets and makes you level it up again even then it doesn’t give you any progress for the challenge .Please make this issue known if you are having the same experience.
