Triple Take trophy not popping up

@ak2481 Same here.

@UnwaryCoin I continued and finally got it. I was trying to get it from three Flame Beetles but it wasn't working, but on the way back to the Mantis I saw three rocket launcher troopers and ,after a few attempts and having to go down a zip line, rest, and going back up to refresh, I managed to kill them in one lightsaber throw and get the trophy.
