Having Trouble Importing Members

We are using Ultimate Member plugin (https://ultimatemember.com/). I would like to import many members using content from a spreadsheet. I exported a member which I entered in manually via Ultimate Member registration and then filled out a test import member using all of the same fields. When I import the member only the First Name, Last Name, and Email come through. The test user can not log into the site after import either. Any instruction on what could be going wrong here?
