Is it possible that you have not completed all the weekly progression quests within the actual campaign? You can get enough currency to unlock all the stuff in the screen above without actually completing all the weekly (progression) quests within the storyline. But IIRC you have to unlock some of the store items by completing certain quests in the within the zone first.

1: what autumnwitch said above, you got the campaign currency to finish it out, but didn't complete the progression (yellow) quests.
2: you haven't finished all 6 milestones. To complete a milestone, pretty sure you have to claim the reward, which you have not done.
