(Solved) New users expired on M5 fresh install

While running M4 I renamed all the users by putting a 1 at the end of the username.
I then did a fresh install of M5, / partition was formatted but /home was not.
When I tried to add new users using MCC they are immediately marked as expired.
This is true even if I add a user that wasn't present when machine ran M4.
I cannot edit these users either, any changes I make to the details in MCC are not saved as when I try to edit an account again the old vales are still present.
How can I add users so they are not immediately expired?
Thank you
