Same here.. Been trying to unlock rapid fire for the last officer weapon finally got 250/250 kills however the career doesn't highlight that I've completed it. Says 250/250 however can't claim the reward. Double checked in collection to see if maybe I can still equip the attachment however says I need to claim or complete the milestone which I have... tried logging out and logging in again however still can't claim the attachment milestone. Had a similar issue this morning as well with the Last Jedi star fighter assault milestones logging out and in worked for that after a few minuets however this one doesn't seem to wanna do it.
