Too many incorrect and confusing entries

I purchased the year upgrade for the Carb Manager app, and now I'm questioning that. I'm finding too many incorrect entries, and too many entries in general. Example: I searched for grape tomatoes. The top result is just plain "grape tomatoes". I entered 6 tomatoes and got 1 net carb. This is definitely incorrect. That should have been 4 net carbs (and I probably wouldn't have chosen that many then). A search for "grape tomato" brings up 30 options with varying carb counts. How is this helpful? How are others dealing with this? How to pick the "correct" entry. A cherry tomato is a cherry tomato, no matter what store it came from.
