Not being able to cancel and back out of a level

I passed a level but the next level did not unlock on the map. So I clicked on the level I just completed and hit the back button to cancel and it said I would lose a life if I didn't play that level. The game use to let you cancel and get out of a level without playing and not lose a life. I forfeited the life backed out and all of the sudden my next level unlocked. So I lost a life for no reason.
