Looking again at those they do not make sense.  df is showing / as 28G
but you say baobab shows it as 13.5G.  Are you sure you are reading
the baobab display correctly?  If you hover over the icons one will
say Scan Filesystem.  Click that and it will scan the whole lot (go
and have a cup of coffee) and show you where the space is used.
