Chris,

That is because incremental backups are uniquely named.
They are forced "inactive" (deleted) when a new full
backup is created.

Try this:

  Version Data Exists : 2
  Version Data Deleted : 2
  Retain Extra Versions : 20
  Retain Only Version : 20

Having "Version Data Deleted" as 0 is causing the problem.

Thanks,

Del
