This is not a bug, this is simply an update.

Eve recently updated the amount of moves that we all get. I assume you're a Basic user.

Previously, Basic users got 30 moves. Recently (like yesterday) that got updated to 50. So now, all Basic users get 50 moves.

Since you bought an extra 5 moves, that still goes on top of the new move update. So, now, you get 50+5=55 moves every time.

(Don't worry, you weren't the only one who was confused when it came out)
