If you only sideload books, it's best to give each Kobo device in the family a different log in email address. That way, you will not end up with each other's shelves. The shelves are synced to the server (and sometimes multiplied there due to a bug).
So, I would log out of the new Glo (from settings), and then log in again with a new Kobo account.
