I clicked "Clear / Delete All Columns" then > "Generate Column Names . Only my 3 columns show up on the module configuration > clicked save. Tried the export and still have the extra columns.
I first tried to manually add my 3 columns and had the same result as above.
I then tried "Clear / Delete All Columns" (available columns shows empty) then > save. Clicked the export link and receive a critical error: Invalid column name 'RowID'".
I first tried this with a "clean module" and on the view template page, simply clicked save/ exit (i miss my "save and exit" like on DF). I had no view, simply the export link (with a bunch of white CR's where the data should be (I was also hoping to use this module as a user export for multiple sql statements, however, the view still shows as many rows as the data exist, just blank without the view tokens)? Opening the xls file still showed the extra columns.
