Images and Text added to Collection Items aren't linking

Nothing I add into a Collection Item is connecting to my CMS? I have tried a number of things but nothing seems to work. Is this an issue with a new account?

Hey Michael,
You haven’t connected the element to anything.

Click the purple dot to bind it to a CMS field.
