Users don't appear as registered?

I imported a single user into my website with the plugin and it works fine, however when I look for that user in the user list on the front end of the website, she doesn’t appear in the list. Do you know why? I haven’t a clue.

After importing, the users should appear on this list.

Otherwise, after testing a few plugins, this is the best one for my needs!

Thanks.
