Hydraflow - Precipitation data is not matching

I am running some calculations to determine my peak flow using the scs method. When a input my data, the program asks me to input my 2 year 24 hour storm. Then I run the calculations based on the storm event I want to calculate (2 year, 5 year, 10 year, etc). When it gives me the peak flow, everything seems to be fine, but the precipitation data doesn't match what I have for the storm event (it's always lower than the precipitation I have). I have attached images of what is going on. All of my storms are there. Am I Doing something wrong? I thought it was a range of precipitation approximation, but it doesn't seem to be the case. Can anybody tell me what's happening?

Perhaps if you can post your .gpw file someone can help.

It's your Hydrograph file.

Autodesk says the file format is not supported.

If you are using Hydraflow Hydrographs Extension in your Civil 3D, you should be saving a file like *.gpw.
