Unable to set up Teams Starter Pack

The President of our 4 person company, subscribed to the Teams Starter Pack and made me an admin. When I look at the Team (So far it's only the two of us), I can see his personal vault, but not his work vault, which is the opposite of what he intended. He has asked me to figure out what's wrong and I've tried looking but can't find a way to address this. HELP.
