When you make changes to your EPUB and send it to the device, the table of contents may become corrupted, regardless of whether you actually moved things around or not. It does not happen always, but it is baffling when it does happen.

The solution is thus to keep that option unchecked and to allow Kobo to treat your new uploads as new books. This ensures that no stray cache data is interfering with it.
That's not the solution. That's actually more of a hassle then it needs to be. Leave that option checked. If you've made changes to the ToC, after you plug your Kobo in for the 2nd time to update the metadata, select the eBooks that you've changed the ToC and with the Kobo Utilities plugin, select Update ToC for selected books. That will update the ToC in the database so you won't have any issues with the ToC.
