Daily challenges

I have a problem with the daily challenges. I’ve got 7/7 daily challenges then I have to be on 8/7 but it’s return back to 7/1 !!! Why. I was getting 0.2 gold and when I reached 7/7 I have to get 0.3 gold but it’s return back !!! And I’m doing the daily challenges every day continuously
