Log out / log on drops the database where all info (including shelves) are stored.
If you had done a sync via WiFi or Kobo desktop the names of the shelves would have been saved but only any kEpubs bought from Kobo; names of ePubs on shelves is not synced to Kobo.
On the other hand if the books and shelves were managed via calibre then they will be recreated by calibre.
