What is going on here??

I had to re-down the app and it took away the the additional features I purchased. Such as landscape mode, search radius and no adds. What gives? Do you expect me to pay for them again? Also, the program acts screwy at time. Restaurants you selected as a favorite dont always show up highlighted. And ones you didnt select sometimes do. The app is full of bugs!!
