Thanks Jonas, I found my issue and it was an oversight on my part. I did not realize the geometric mean doesn't get automatically updated to the input in the Amount column. Since I copied the process and then changed the Amount input, I did not, in turn, change the Gmean in the uncertainty column. Wouldn't it be best to auto-update to the deterministic Amount entered? I see gsigma is updated automatically when I change the Data quality entry column.
