Data Shuttle Problem- No column header options

I'm trying to use data shuttle to link an excel file to a smartsheet file. The header columns on my smartsheet match with the header columns on my excel file. However, when I go to create the mapping, I don't see an option for my column header names from the excel file, it only shows: "Version".

Additionally, if I deselect the column header option it only shows me options to map two of my columns, but not all of them.

I have no idea where it's pulling version from. These are the column headers on the Excel Sheet:

Any help would be appreciated.

Thank you
