After importing a CSV file of contacts, the rows with errors can be downloaded and fixed. Today I noticed that the "Reason" column is missing from this error list. For example the Import_errors.csv file might contain this:
"Line Number","Reason","First Name","Last Name","Email - Home"
"1","Joe","Blow","[email protected]"
So in this example there are 5 column headers but only 4 data elements. That is consistently how these files appear, one column is missing. This is Civicrm 5.35.1 on Wordpress 5.7.1. Any ideas?
