Splunk Fundamentals 1 - Module 3 Lab - adding a new power user

Greetings, In the pop-up window where I can add a new user, I can select username, name and then email address. After that, if I click the Tab key, the selector does not move to the "password" and "confirm password" fields. (Running Ubuntu 18.04 on a Parallels VM) Thank you in advance for any help Mits
