Farmboy Luke Challenge

I have Battlefront 2 (2017) for my PS4, and have no idea how the events are supposed to work. I know back in the fall Farmboy Luke and Princess Leia were released with challenges to get them for a limited time. While playing today, I saw I had challenges for both, the one I care more about being Luke, needing 5,000 kills with him. The reward says "Farmboy", which I can only assume means the appearance. Does anybody know if I complete this challenge will it give me the Luke style? Does anybody else have this challenge? I can't find any information about it anywhere.
