New contacts uploaded via CSV not added to contact group

I took the following steps:
* on the contacts page: https://go.vumi.org/contacts/people/
* clicked the "Import contacts" button
* selected "import a spreadsheet" from the pop up
* selected a CSV from my local files
* defined a new group name (n.b. I did not decide to add the contacts to an existing group)
* clicked "upload contacts" button
* matched the sample to the fields provided in the ensuing pop up and clicked 'ok'
* am then directed to the groups page where the contacts that were in my CSV are displayed
* I then click on 'groups' in the left nav
* I click on the name of the group "Sample Group"
* I am directed to the "Sample Group" page that displays no contacts

Also: I had three contacts in my CSV, one of those contacts is displayed twice. i.e. a total of 4 contacts are displayed.
