UPDATE: it works now after adding a blank summary column to the file... however, I go through the update and no labels are being added. Do I need to add the label values first to the list in JIRA before uploading so it has one to add that exists?
My csv file is this:
issue key,summary,labels
DEV-308,,Stripe
Then result in ticket is this:

Original ticket:
I am using the old way to external system import csv.
My file with contains an issue key and labels column to update labels on the existing jira issue.
However, I can't click next.
Please let me know.. I have 1000s to update.
