No progress in Last Jedi's challenges

Same problem with "Blast them All".  Counter stuck at 194/200.  Been in and out of the main menus and the game and had way more than 6 kills on all 4 of the trooper classes, so it should easily have completed by now.  None of the 4 classes progresses the kills anymore.  So cheezed, as this is the last thing to complete and only a few days left to get the rewards.  Fix NOW, please.  Or at least extend the time period to complete these broken challenges until after they have all been fixed.
