All of these books are ePUBs and have been run through Calibre's converter prior to loading. Both Calibre and the Kobo are running latest version of their respective software. I use the Kobo Utilities plug-in in Calibre to manage shelves.

Anyone have any thoughts on this?
As @theducks said, it is most likely bad code. Open the book in the calibre editor and run the Check Book tool (the little bug icon) on it. When this happens to me, it is either a mismatched tag, or an ampersand or other character that needs to be changed to the html entity or unicode character.

And EPUBCheck is overkill for just about any problem where the book loads but has errors. The check in the editor will find almost everything that would cause a problem when sideloading an epub to just about any device that accepts epubs. And that definitely applies to Kobo ereaders.
