Query: Automatic stop doesn't

Have had this for less than a week, but it has been consistent. It grinds well for my purposes, drip coffee - but doesn't stop grinding as advertised. I had it set for 12 cups, and was getting the cups down, etc. while it was grinding.When I looked, it had completely filled the hopper and was still grinding. I have tried it on different quantities and back on 12 cups, and always the same results - it grinds away without regard to the setting. It is going back to the retail store this weekend.
