For some reason this was glitching for me even beyond just the final achievement.

I completed all the maps at 100%, but the different scenario achievements weren't unlocking at all. I tried deleting my progress, but that didn't work. I ended up deleting my save file from everywhere (including the cloud). Once I went through the maps again, each achievement popped, including the last one.

Obviously, you'll your progress toward the online maps, so if you've been working on those, finish the online before clearing your save files.

Hope this helps!
