New users added via Batch Create do not receive the set password link

If I add a new user to the site manually, they immediately receive a ‘Your username and password info’ email containing a link they need to follow in order to set their password:

To set your password, visit the following address:

http://pci-learning.com/wp-login.php?action=rp&key

When I add users via Batch Create they receive an email with these instructions (square brackets included):

Password: [User Set]

http://pci-learning.com/wp-login.php

This does not seem to work for new users.

Many thanks for your help

Best wishes
