Imported contact not showing when To: is used

[dwolf]

I imported my csv file into Outlook 2013 exactly as instructed from many sources... Here is how I did it. https://www.youtube.com/watch?v=eIrOLs91qtE

I can see in the People tab on the bottom all of my contacts.

I go to compose an email and when I press the To: tab my address book is empty. I use the drop down menu and try the two options there but it shows no contacts.
