Glitch- how to fix?

Hey, my calories doubled and I can't reverse it, what do?
I had input all the food for the day, but then decided to delete the tabs (breakfast, lunch, etc) and have just 1 (whole day's food). After doing it, the food disappeared, so I input it again under the same system, but the site and app are counting both, thus doubling my daily calories, yet it only shows the latest food I added in the original portions. How to fix this?
