Graph is doubling the total amount

I made a graph to track the total number of things per day, including an overall total. The problem is that the total is double the correct amount. How do I fix this?

I don't know much graphs but I did look at the wb you supplied. There is a primary and secondary for that top line. When you select primary, it doubles, select secondary and it is correct. I don't know what that means, it's just what I noticed.

The line is correctly positioned for the chosen chart type -- a stacked line. Were you expecting to use a regular line chart?
