CSV to CSV Removing headers

We have recently encountered an issue when outputting to a CSV the Default value is not populating and removing the column as well as any other columns with no data. 

Thanks

Hi Chris,

With the provided information’s I can’t image what you try to do. Could you please describe what you have done and how I could reproduce your issue?

Some screenshots, test data or your created definition would be also helpful.
 

See Below, it seems like it is not processing anything at all now as both input and output are the same

Hi Chris,

sorry, I can´t believe this 

For me the screenshot just shows your input file! Are you sure that you are comparing the right versions? Please check the create and/or modification date of the current output file as well.

Attached you´ll find a brief CSV column header example, this is working as expected. Please try to run this one.

For further investigation I need your created definition and some test data to reproduce your issue.
