Kraber Trial 3 Kills While ADS Not Increasing from 99 to 100

Hey there I have done every Kraber trial except for the ADS kills it seems to be stuck on 99/100 even after I kill someone and full them while ADS. I've tried with a Kraber headshot, no headshot, with the event kraber, with a normal kraber, in Trios, Wildcard, Mixtape Gun Run and Bot Royal I have tried to get it but it appears bugged for some reason and isn't increasing from 99->100, thanks in advance for looking into this for me I am trying to get every gun trial completed and this bug is stopping that for being possible.
