After enabling Journeys I don't see the Assign Journey button

Summary:

I've enabled the Journey Admin Profile Values. When I go into the Journey icon via My Client Groups and find the Journey to assign within 'Explore', I'm unable to assign the Journey. Typically after selecting the Journey, I will have the drop-down button for Assign to Self or Others but those buttons are not showing.
