Steam Achievements have a bug?

I just completed the game and did all puzzles, including bonus puzzles, and my rank is "Puzzle Agent!". And yet "Rank: Puzzle Agent" remains locked, plus another hidden achievement is locked. Is the rank achievement broken by any chance? (I'm playing on the PC)

(Side-note: I'm assuming the last hidden achievement would be to perfect all puzzles? Though if that's the case I see no reason to have it hidden.)

    You not just need to have a "Puzzle Agent!" rank, but also solve all the puzzles with 10 stars.
    The last secret achievement is
    for an extra puzzle that unlocks when you get the "Puzzle Agent!" rank with 10 stars on each puzzle.
