Hi All!
So, we've had a company realignment and I'm trying to bulk update all our pre-existing Users details. According to Atlassian this should be fairly straightforward, but mine just keep creating new users
This is the information I'm going off: Import data from a CSV file | Atlassian Support

My spreadsheet I'm using to import:

My config file I'm using to import:

The available fields I get when I import:
Some notes:
- I have 'Status' in my spreadsheet, this does also not work it puts everything into default status whether I have specified it or not.
- Status is not in my config file, as I wanted to see if it made any difference or not
Any suggestions as to what I'm missing as to why it's not updating users and just creating new ones instead?
Thanks!
