Re: Problem with attachments
From what I have seen, if those were unlocked playing a solo bot match while still under the set level cap it doesn’t always register in the system properly as unlockable until you play some full XP multiplayer rounds and get more kills using that same weapon.
E.g., you enter a bot match close to your level cap, within a few minutes of play you reach the level cap on advancement (limited XP match) but the round isn’t over and you continue to use the same weapon racking up 100's of bot kills. At the end of the round it will show you have unlocked more things over the cap than should have been allowed. That’s when it gets buggy and doesn’t register the unlocks correctly. The attachments will show in the XP bar as fully unlocked like in your picture, but the item won’t actually unlock until the proper number of kills have been obtained by playing in a full XP game mode against other players.
