yep also have this problem, I noticed that attachments that has the mastery word in it as the requirement, those only works in multiplayer, which is not what EA promised about shared progression. Only those without the word" Mastery" work in solo/coop AI, this should be changed, enable progress for all game modes regardless of how fast people level. So please EA, please deliver your promise of equal shared progression, its the main selling point for me, since i'm huge on AI with friends, portal and solo/coop with AI should have weapon and level progression as normal as multiplayer. thank you
