If you have a corrupt database, sometimes you can export it and import it to a new database and copy the new one over top of the old one and _THEN_ reboot and it fixes it. But damage to the database form this can accumulate until it isn't corrupt but isn't right either.
A better solution when you have a corrupt database is to copy an older backup in and then reboot.
And if that doesn't work, just *delete* the database and and the kobo will do a soft factory reset that doesn't delete your side loaded books. Log back into your account and it will reimport them. However screen savers and dictionaries still get deleted.
