Achievements Not Showing Up

A number of achievements that I've completed aren't showing as completed and thus not getting the rewards. I created a clan, spent the gems on it, and it doesn't show that I did so in my achievements. The cogs and machine game achievements also aren't working, they show me only having earned 3 out of 120 stars but I've completed all five pages of runs on both games with most of them being three stars. Please fix!
