Admin sees a reports multiple versions by the same "created" (i.e balance sheet) ending with -1, -2, and -3. The creator sees only the original version. Why?

For example:

Lucianne only sees the first report listed, but the admin sees all of them despite the "Created" being listed as Lucianne.  What is going on?  How can I determine when these versions were created?  Is this some poor man's version of revision control?

Name                                           Created
