100% the campaign, still locked content

I beat the campaign (legendary 100% and laso) and there is still a few stances and a weapon key chain thing (can’t remember what it’s actually called) that say there are unlocked via campaign. Do I have to some hidden objective or is just pointing to an expansion to the campaign later down the line?

I dunno. I’ll have to check a list as I have locks too. I do know that if you were offline when opening a crate it doesn’t unlock for multiplayer.

At least two stances are unobtainable or not found yet!

They are obtainable through the campaign but nobody know what needs to be done to unlock those items. Seems to be a mystery that is yet to be solved.
