I figured out what happened. There was an error a SQL error in the logs showing langcode cannot be null. I looked at the header of my csv file and the column titles langcode and body were concatenated into the langcode column header. I fixed that and the import worked!
Note
the "Click Here and Download Sample CSV" butting creates a file with this issue. There is no body column, and the word body is appended to the langcode field [langcodebody]
