Am I missing something or shouldn't all this be visible as to what's been already added?

I have 5 banner ads in the homeslide1 group.
How can I edit a particular one? I don't see how to view all the banner ads within the slider in the configuration of homeslide1
Any help is appreciated.

The same goes for the Flexible footer - Share and Connect
I only use Facebook so how can I remove the rest?
