I'm not even sure how to search this issue... All attempts have come up empty...

I have data pulled into a stacked line chart. The lines should all show trending numbers separately from each other (no overlap). As it stands, the data labels are correct but the placement on the chart is incorrect. See attached screenshot. Help???

The bottom (purple) line seems to be correct.
The rest are not plotting properly. You can see the numbers go down in value but the line goes up. I have no idea how to fix this.....
