Food not selling unless game is open!!

Like the game but recently in the past month, my food filled up all the counters from a challenge last week and food wont sell unless I am open in the app. This is getting VERY frustrating I cant bake anything because all the counters are filled up. They have been filled up for a few weeks now. FIX IT PLEASE!
