Does anyone have experience with the 3D Map feature?

I have data that goes with physical addresses and it helps to see it spread out on a map. When I first created the spreadsheet, I placed my data in the Height field and it was automatically selected to show the sum of the data.

Now when I've updated the data on the spreadsheet and refresh the data, now it will only allow me to pick the count for the data and nothing more. I've gone over the data numerous times now making sure that everything was actually a number so it would sum the data but it doesn't seem to have done anything.
