Where are my files?

I have a "Developer Account"

I have a custom app where files are created to my Box account.

However, when I log in to my Box.com account, I don't see anything in "All Files"

I also see nothing when I go to Admin Console > Content.

When I go to Admin Console > Insights, I can see 6.1GB of documents but can't access them anywhere.

Where are my files?
