I really love this game and as such want to complete all the achievements. However the game is not showing my progress for the completionist and super completionist achievements. I have 87 blue and gold stars but it’s still showing as only 0. 
My achievements might be glitched
That’s weird. Tried out and it works fine for me…
Oooh, Steam achievements! I thought you were talking about the in-game ones. Are you in-game ones correct? Steam tends to be weird regarding some achievements.
The in-game ones are fine. Guess I’ll just have to suffice with that.
I had the same issue, but the achievement got triggered all right in the end. It’s just the progress tracking that’s glitched.
