Data Shuttle - Unable to Map / Not Mapped

Hi there, I've been trying to set up a Data Shuttle workflow to replace all data with new attachment uploaded in another smartsheet. It was unable to map ANY columns even I try with the exact same data. It does not help either with changing any of the parameters in Data Shuttle.

So the issue was that Data Shuttle will not be able to identify any columns if the source file (the attachment) contains wrapping format. The source attachment must be unwrapped before uploading in order for Data Shuttle to map the columns (may not be all but I managed to have one matched automatically.)

Wondering if there can be fix to this so I don't need to change anything in the source file.

Thank you :)
