Created new recipe but calories logged in differently. Found a fix!

I created a recipe for a salad (1 serving) and the app calculated it as 406 but when I saved and logged it in my diary it logged 334 calories. According to my calculations, it didn't log calories for ingredients under 30 calories (lemon juice, cumin, fresh mint, etc). So I doubled the recipe as 2 servings and this brought the calories closer to the accurate total but is still off by 36 calories. I usually don't log calories for spices / lemon juice / herbs . I didn't think they added up to much. But sometimes I wanted to refer to the recipe adder in MFP app to remake a recipe so this time i included all the ingredients, not just the ones with the most significant amount of calories. Anyway, if you've encountered this glitch and it frustrates you, try doubling or quadrupling the recipe to get a more accurate calorie count for one serving. Good luck!
