Changelog for DIM states:

5.33.0(6/15/2019)
CSV exports now include item sources. These match the DIM filter you can use to find the item.

The issue lies in line 101~117. Variable names are hard-coded to specific columns in the array, versus assigning variable names based on the header row of the CSV being processed.
A shift of +1 to each row[x] after line 109 should correct the issue for now, but should expect to break if DIM developers add another data column within the existing data array instead of appending it.
