This First position CPC dimension is having a number format problem, instead of "3.23" it will bring something like 323000000. I am using adwords as a source on the supermetrics for spreadsheets.
Also, why is it a dimension? it should be a metric enabled when using keyword as a dimension.
I will send a request to check and fix the formatting of that field if it's supposed to be a decimal.
The reason it's a dimension is that it's defined as one (aka an attribute) in the AdWords API, not as a metric.
